edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

treewide: Fix function prototypes for module_param_call()
Several function prototypes for the set/get functions defined by
module_param_call() have a slightly wrong argument types. This fixes
those in an effort to clean up the calls when running under type-enforced
compiler instrumentation for CFI. This is the result of running the
following semantic patch:
@match_module_param_call_function@
declarer name module_param_call;

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:
$ tree /sys/bus/edac/
/sys/bus/edac/
├── devices
│ ├── all_channel_counts -> ../../../devices/system/edac/mc/mc0/all_channel_counts
│ ├── csrow0 -> ../../../devices/system/edac/mc/mc0/csrow0

│ ├── mc -> ../../../devices/system/edac/mc
│ └── mc0 -> ../../../devices/system/edac/mc/mc0
├── drivers
├── drivers_autoprobe
├── drivers_probe
└── uevent
On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"

So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,

There's one drawback on this patch: driver-specific sysfs

The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.

one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

it is putting everything under the same directory:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:

So, we need to create a per-MC bus, in order to have its own namespace.

nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"

So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.

code to struct device.

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:
$ tree /sys/bus/edac/
/sys/bus/edac/

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: Initialize the dimm label with the known information
While userspace doesn't fill the dimm labels, add there the dimm location,
as described by the used memory model. This could eventually match what
is described at the dmidecode, making easier for people to identify the
memory.
For example, on an Intel motherboard where the DMI table is reliable,
the first memory stick is described as:
Memory Device
Array Handle: 0x0029
Error Information Handle: Not Provided
Total Width: 64 bits
Data Width: 64 bits
Size: 2048 MB
Form Factor: DIMM
Set: 1
Locator: A1_DIMM0
Bank Locator: A1_Node0_Channel0_Dimm0
Type: <OUT OF SPEC>
Type Detail: Synchronous
Speed: 800 MHz
Manufacturer: A1_Manufacturer0
Serial Number: A1_SerNum0
Asset Tag: A1_AssetTagNum0
Part Number: A1_PartNum0
The memory named as "A1_DIMM0" is physically located at the first
memory controller (node 0), at channel 0, dimm slot 0.
After this patch, the memory label will be filled with:
/sys/devices/system/edac/mc/csrow0/ch0_dimm_label:mc#0channel#0slot#0
And (after the new EDAC API patches) as:
/sys/devices/system/edac/mc/mc0/dimm0/dimm_label:mc#0channel#0slot#0
So, even if the memory label is not initialized on userspace, an useful
information with the error location is filled there, expecially since
several systems/motherboards are provided with enough info to map from
channel/slot (or branch/channel/slot) into the DIMM label. So, letting the
EDAC core fill it by default is a good thing.
It should noticed that, as the label filling happens at the
edac_mc_alloc(), drivers can override it to better describe the memories
(and some actually do it).

So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: Initialize the dimm label with the known information
While userspace doesn't fill the dimm labels, add there the dimm location,
as described by the used memory model. This could eventually match what
is described at the dmidecode, making easier for people to identify the
memory.
For example, on an Intel motherboard where the DMI table is reliable,
the first memory stick is described as:
Memory Device
Array Handle: 0x0029
Error Information Handle: Not Provided
Total Width: 64 bits
Data Width: 64 bits
Size: 2048 MB
Form Factor: DIMM
Set: 1
Locator: A1_DIMM0
Bank Locator: A1_Node0_Channel0_Dimm0
Type: <OUT OF SPEC>
Type Detail: Synchronous
Speed: 800 MHz
Manufacturer: A1_Manufacturer0
Serial Number: A1_SerNum0
Asset Tag: A1_AssetTagNum0
Part Number: A1_PartNum0
The memory named as "A1_DIMM0" is physically located at the first
memory controller (node 0), at channel 0, dimm slot 0.
After this patch, the memory label will be filled with:
/sys/devices/system/edac/mc/csrow0/ch0_dimm_label:mc#0channel#0slot#0
And (after the new EDAC API patches) as:
/sys/devices/system/edac/mc/mc0/dimm0/dimm_label:mc#0channel#0slot#0
So, even if the memory label is not initialized on userspace, an useful
information with the error location is filled there, expecially since
several systems/motherboards are provided with enough info to map from
channel/slot (or branch/channel/slot) into the DIMM label. So, letting the
EDAC core fill it by default is a good thing.
It should noticed that, as the label filling happens at the
edac_mc_alloc(), drivers can override it to better describe the memories
(and some actually do it).

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: Initialize the dimm label with the known information
While userspace doesn't fill the dimm labels, add there the dimm location,
as described by the used memory model. This could eventually match what
is described at the dmidecode, making easier for people to identify the
memory.
For example, on an Intel motherboard where the DMI table is reliable,
the first memory stick is described as:
Memory Device
Array Handle: 0x0029
Error Information Handle: Not Provided
Total Width: 64 bits
Data Width: 64 bits
Size: 2048 MB
Form Factor: DIMM
Set: 1
Locator: A1_DIMM0
Bank Locator: A1_Node0_Channel0_Dimm0
Type: <OUT OF SPEC>
Type Detail: Synchronous
Speed: 800 MHz
Manufacturer: A1_Manufacturer0
Serial Number: A1_SerNum0
Asset Tag: A1_AssetTagNum0
Part Number: A1_PartNum0
The memory named as "A1_DIMM0" is physically located at the first
memory controller (node 0), at channel 0, dimm slot 0.
After this patch, the memory label will be filled with:
/sys/devices/system/edac/mc/csrow0/ch0_dimm_label:mc#0channel#0slot#0
And (after the new EDAC API patches) as:
/sys/devices/system/edac/mc/mc0/dimm0/dimm_label:mc#0channel#0slot#0
So, even if the memory label is not initialized on userspace, an useful
information with the error location is filled there, expecially since
several systems/motherboards are provided with enough info to map from
channel/slot (or branch/channel/slot) into the DIMM label. So, letting the
EDAC core fill it by default is a good thing.
It should noticed that, as the label filling happens at the
edac_mc_alloc(), drivers can override it to better describe the memories
(and some actually do it).

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"

So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

edac: rewrite the sysfs code to use struct device
The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:
