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.

ahci: Add generic MSI-X support for single interrupts to SATA PCI driver
This patch adds generic MSI-X support for single interrupts to the
SATA PCI driver. MSI-X support is needed for host controller that only
have MSI-X support implemented, but no MSI or intx. This patch only
adds support for single interrupts, multiple per-port MSI-X interrupts
are not yet implemented.
The new implementation still initializes MSIs first. Only if that
fails, the code tries to enable MSI-X. If that fails too, setup is
continued with intx interrupts.
To not break other chips by this generic code change, there are the
following precautions:
* Interrupt ranges are not enabled at all.
* Only single interrupt mode is enabled for msix cap devices. Thus,
only one interrupt will be setup.
* During the discussion with Tejun we agreed to change the init
sequence from msix-msi-intx to msi-msix-intx. Thus, if a device
offers msi and init does not fail, the msix init code will not be
executed. This is equivalent to current code.
With this, the code only setups single mode msix as a last resort if
msi fails. No interrupt range is enabled at all. Only one interrupt
will be enabled.
tj: comment edits.
Changes of the patch series:
v5:
* updated patch subject that the patch only implements single IRQ
* moved Cavium specific code to a separate patch
* detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI
instead of vendor/dev id
* added more comments to the code
* enable single msix support for all kind of devices (removing strict
check)
* rebased onto update libata/for-4.2 with patch 1, 2 applied
v4:
* removed implementation of ahci_init_intx()
* improved patch descriptions
* rebased onto libata/for-4.2
v3:
* store irq number in struct ahci_host_priv
* change initialization order from msix-msi-intx to msi-msix-intx
* improve comments in ahci_init_msix()
* improve error message in ahci_init_msix()
* do not enable MSI-X if MSI is actively disabled for the device
v2:
* determine irq vector from pci_dev->msi_list
Based on a patch from Sunil Goutham <sgoutham@cavium.com>.

libata: make reset related methods proper port operations
Currently reset methods are not specified directly in the
ata_port_operations table. If a LLD wants to use custom reset
methods, it should construct and use a error_handler which uses those
reset methods. It's done this way for two reasons.
First, the ops table already contained too many methods and adding
four more of them would noticeably increase the amount of necessary
boilerplate code all over low level drivers.
Second, as ->error_handler uses those reset methods, it can get
confusing. ie. By overriding ->error_handler, those reset ops can be
made useless making layering a bit hazy.
Now that ops table uses inheritance, the first problem doesn't exist
anymore. The second isn't completely solved but is relieved by
providing default values - most drivers can just override what it has
implemented and don't have to concern itself about higher level
callbacks. In fact, there currently is no driver which actually
modifies error handling behavior. Drivers which override
->error_handler just wraps the standard error handler only to prepare
the controller for EH. I don't think making ops layering strict has
any noticeable benefit.
This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and
their PMP counterparts propoer ops. Default ops are provided in the
base ops tables and drivers are converted to override individual reset
methods instead of creating custom error_handler.
* ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs
aren't accessible. sata_promise doesn't need to use separate
error_handlers for PATA and SATA anymore.
* softreset is broken for sata_inic162x and sata_sx4. As libata now
always prefers hardreset, this doesn't really matter but the ops are
forced to NULL using ATA_OP_NULL for documentation purpose.
* pata_hpt374 needs to use different prereset for the first and second
PCI functions. This used to be done by branching from
hpt374_error_handler(). The proper way to do this is to use
separate ops and port_info tables for each function. Converted.

libata: implement and use ops inheritance
libata lets low level drivers build ata_port_operations table and
register it with libata core layer. This allows low level drivers
high level of flexibility but also burdens them with lots of
boilerplate entries.
This becomes worse for drivers which support related similar
controllers which differ slightly. They share most of the operations
except for a few. However, the driver still needs to list all
operations for each variant. This results in large number of
duplicate entries, which is not only inefficient but also error-prone
as it becomes very difficult to tell what the actual differences are.
This duplicate boilerplates all over the low level drivers also make
updating the core layer exteremely difficult and error-prone. When
compounded with multi-branched development model, it ends up
accumulating inconsistencies over time. Some of those inconsistencies
cause immediate problems and fixed. Others just remain there dormant
making maintenance increasingly difficult.
To rectify the problem, this patch implements ata_port_operations
inheritance. To allow LLDs to easily re-use their own ops tables
overriding only specific methods, this patch implements poor man's
class inheritance. An ops table has ->inherits field which can be set
to any ops table as long as it doesn't create a loop. When the host
is started, the inheritance chain is followed and any operation which
isn't specified is taken from the nearest ancestor which has it
specified. This operation is called finalization and done only once
per an ops table and the LLD doesn't have to do anything special about
it other than making the ops table non-const such that libata can
update it.
libata provides four base ops tables lower drivers can inherit from -
base, sata, pmp, sff and bmdma. To avoid overriding these ops
accidentaly, these ops are declared const and LLDs should always
inherit these instead of using them directly.
After finalization, all the ops table are identical before and after
the patch except for setting .irq_handler to ata_interrupt in drivers
which didn't use to. The .irq_handler doesn't have any actual effect
and the field will soon be removed by later patch.
* sata_sx4 is still using old style EH and currently doesn't take
advantage of ops inheritance.

class inheritance. An ops table has ->inherits field which can be set
to any ops table as long as it doesn't create a loop. When the host
is started, the inheritance chain is followed and any operation which
isn't specified is taken from the nearest ancestor which has it
specified. This operation is called finalization and done only once
per an ops table and the LLD doesn't have to do anything special about
it other than making the ops table non-const such that libata can
update it.
libata provides four base ops tables lower drivers can inherit from -
base, sata, pmp, sff and bmdma. To avoid overriding these ops
accidentaly, these ops are declared const and LLDs should always
inherit these instead of using them directly.
After finalization, all the ops table are identical before and after
the patch except for setting .irq_handler to ata_interrupt in drivers
which didn't use to. The .irq_handler doesn't have any actual effect
and the field will soon be removed by later patch.
* sata_sx4 is still using old style EH and currently doesn't take
advantage of ops inheritance.

libata: implement and use ops inheritance
libata lets low level drivers build ata_port_operations table and
register it with libata core layer. This allows low level drivers
high level of flexibility but also burdens them with lots of
boilerplate entries.
This becomes worse for drivers which support related similar
controllers which differ slightly. They share most of the operations
except for a few. However, the driver still needs to list all
operations for each variant. This results in large number of
duplicate entries, which is not only inefficient but also error-prone
as it becomes very difficult to tell what the actual differences are.
This duplicate boilerplates all over the low level drivers also make
updating the core layer exteremely difficult and error-prone. When
compounded with multi-branched development model, it ends up
accumulating inconsistencies over time. Some of those inconsistencies
cause immediate problems and fixed. Others just remain there dormant
making maintenance increasingly difficult.
To rectify the problem, this patch implements ata_port_operations
inheritance. To allow LLDs to easily re-use their own ops tables
overriding only specific methods, this patch implements poor man's
class inheritance. An ops table has ->inherits field which can be set
to any ops table as long as it doesn't create a loop. When the host
is started, the inheritance chain is followed and any operation which
isn't specified is taken from the nearest ancestor which has it
specified. This operation is called finalization and done only once

libata: make reset related methods proper port operations
Currently reset methods are not specified directly in the
ata_port_operations table. If a LLD wants to use custom reset
methods, it should construct and use a error_handler which uses those
reset methods. It's done this way for two reasons.
First, the ops table already contained too many methods and adding
four more of them would noticeably increase the amount of necessary
boilerplate code all over low level drivers.
Second, as ->error_handler uses those reset methods, it can get
confusing. ie. By overriding ->error_handler, those reset ops can be
made useless making layering a bit hazy.
Now that ops table uses inheritance, the first problem doesn't exist
anymore. The second isn't completely solved but is relieved by
providing default values - most drivers can just override what it has
implemented and don't have to concern itself about higher level
callbacks. In fact, there currently is no driver which actually
modifies error handling behavior. Drivers which override
->error_handler just wraps the standard error handler only to prepare
the controller for EH. I don't think making ops layering strict has
any noticeable benefit.
This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and
their PMP counterparts propoer ops. Default ops are provided in the
base ops tables and drivers are converted to override individual reset
methods instead of creating custom error_handler.
* ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs
aren't accessible. sata_promise doesn't need to use separate
error_handlers for PATA and SATA anymore.
* softreset is broken for sata_inic162x and sata_sx4. As libata now
always prefers hardreset, this doesn't really matter but the ops are
forced to NULL using ATA_OP_NULL for documentation purpose.
* pata_hpt374 needs to use different prereset for the first and second
PCI functions. This used to be done by branching from
hpt374_error_handler(). The proper way to do this is to use
separate ops and port_info tables for each function. Converted.

PCI: Disable async suspend/resume for JMicron multi-function SATA/AHCI
On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at
function 1 doesn't work if it is powered on before the SATA controller at
function 0. The result is that PATA doesn't work after resume, and we
print messages like this:
pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3
irq 17: nobody cared (try booting with the "irqpoll" option)
Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep:
Asynchronous threads for resume_noirq"). Prior to that, we powered on
the functions in order, so this problem shouldn't happen.
e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361")
solved the problem for JMicron 361 and 363 devices. With async suspend
disabled, we always power on function 0 before function 1.
Barto then reported the same problem with a JMicron 368 (see comment #57 in
the bugzilla).
Rather than extending the blacklist piecemeal, disable async suspend for
all JMicron multi-function SATA/PATA/AHCI devices.
This quirk could stay in the ahci and pata_jmicron drivers, but it's likely
the problem will occur even if pata_jmicron isn't loaded until after the
suspend/resume. Making it a PCI quirk ensures that we'll preserve the
power-on order even if the drivers aren't loaded.

libata: convert the remaining SATA drivers to new init model
Convert ahci, sata_sil, sata_sil24, sata_svw, sata_qstor, sata_mv,
sata_sx4, sata_vsc and sata_inic162x to new init model.
Now that host and ap are available during intialization, functions are
converted to take either host or ap instead of low level parameters
which were inevitable for functions shared between init and other
paths. This simplifies code quite a bit.
* init_one()'s now follow more consistent init order
* ahci_setup_port() and ahci_host_init() collapsed into
ahci_init_one() for init order consistency
* sata_vsc uses port_info instead of setting fields manually
* in sata_svw, k2_board_info converted to port_info (info is now in
port flags). port number is honored now.
Tested on ICH7/8 AHCI, jmb360, sil3112, 3114, 3124 and 3132.

ahci: Add generic MSI-X support for single interrupts to SATA PCI driver
This patch adds generic MSI-X support for single interrupts to the
SATA PCI driver. MSI-X support is needed for host controller that only
have MSI-X support implemented, but no MSI or intx. This patch only
adds support for single interrupts, multiple per-port MSI-X interrupts
are not yet implemented.
The new implementation still initializes MSIs first. Only if that
fails, the code tries to enable MSI-X. If that fails too, setup is
continued with intx interrupts.
To not break other chips by this generic code change, there are the
following precautions:
* Interrupt ranges are not enabled at all.
* Only single interrupt mode is enabled for msix cap devices. Thus,
only one interrupt will be setup.
* During the discussion with Tejun we agreed to change the init
sequence from msix-msi-intx to msi-msix-intx. Thus, if a device
offers msi and init does not fail, the msix init code will not be
executed. This is equivalent to current code.
With this, the code only setups single mode msix as a last resort if
msi fails. No interrupt range is enabled at all. Only one interrupt
will be enabled.
tj: comment edits.
Changes of the patch series:
v5:
* updated patch subject that the patch only implements single IRQ
* moved Cavium specific code to a separate patch
* detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI
instead of vendor/dev id
* added more comments to the code
* enable single msix support for all kind of devices (removing strict
check)
* rebased onto update libata/for-4.2 with patch 1, 2 applied
v4:
* removed implementation of ahci_init_intx()
* improved patch descriptions
* rebased onto libata/for-4.2
v3:
* store irq number in struct ahci_host_priv
* change initialization order from msix-msi-intx to msi-msix-intx
* improve comments in ahci_init_msix()
* improve error message in ahci_init_msix()
* do not enable MSI-X if MSI is actively disabled for the device
v2:
* determine irq vector from pci_dev->msi_list

ahci: Add generic MSI-X support for single interrupts to SATA PCI driver
This patch adds generic MSI-X support for single interrupts to the
SATA PCI driver. MSI-X support is needed for host controller that only
have MSI-X support implemented, but no MSI or intx. This patch only
adds support for single interrupts, multiple per-port MSI-X interrupts
are not yet implemented.
The new implementation still initializes MSIs first. Only if that
fails, the code tries to enable MSI-X. If that fails too, setup is
continued with intx interrupts.
To not break other chips by this generic code change, there are the
following precautions:
* Interrupt ranges are not enabled at all.
* Only single interrupt mode is enabled for msix cap devices. Thus,
only one interrupt will be setup.
* During the discussion with Tejun we agreed to change the init
sequence from msix-msi-intx to msi-msix-intx. Thus, if a device
offers msi and init does not fail, the msix init code will not be
executed. This is equivalent to current code.
With this, the code only setups single mode msix as a last resort if
msi fails. No interrupt range is enabled at all. Only one interrupt
will be enabled.
tj: comment edits.
Changes of the patch series:
v5:
* updated patch subject that the patch only implements single IRQ
* moved Cavium specific code to a separate patch
* detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI
instead of vendor/dev id
* added more comments to the code
* enable single msix support for all kind of devices (removing strict
check)
* rebased onto update libata/for-4.2 with patch 1, 2 applied
v4:
* removed implementation of ahci_init_intx()
* improved patch descriptions
* rebased onto libata/for-4.2
v3:
* store irq number in struct ahci_host_priv
* change initialization order from msix-msi-intx to msi-msix-intx
* improve comments in ahci_init_msix()
* improve error message in ahci_init_msix()
* do not enable MSI-X if MSI is actively disabled for the device
v2:
* determine irq vector from pci_dev->msi_list

libata: convert the remaining SATA drivers to new init model
Convert ahci, sata_sil, sata_sil24, sata_svw, sata_qstor, sata_mv,
sata_sx4, sata_vsc and sata_inic162x to new init model.
Now that host and ap are available during intialization, functions are
converted to take either host or ap instead of low level parameters
which were inevitable for functions shared between init and other
paths. This simplifies code quite a bit.
* init_one()'s now follow more consistent init order
* ahci_setup_port() and ahci_host_init() collapsed into
ahci_init_one() for init order consistency
* sata_vsc uses port_info instead of setting fields manually
* in sata_svw, k2_board_info converted to port_info (info is now in
port flags). port number is honored now.
Tested on ICH7/8 AHCI, jmb360, sil3112, 3114, 3124 and 3132.
