[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

changes due to qe_lib changes include:

o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

commit b1c4a9dddf09fe99b8f88252718ac5b357363dc4 ("ucc_geth: Change

in the ucc_geth driver that causes this oops when fixed-link is used:
Unable to handle kernel paging request for data at address 0x00000000
Faulting instruction address: 0xc0151270
Oops: Kernel access of bad area, sig: 11 [#1]

function to use uec_mdio_bus_name().
Also, since we fully construct phy_bus_id in the _probe() routine,
we no longer need ->phy_address and ->mdio_bus fields in
ucc_geth_info structure.
I wish the patch would be a bit shorter, but it seems like the only
way to fix the issue in a sane way. Luckily, the patch has been
tested with real PHYs and fixed-link, so no further regressions
expected.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

ucc_geth: Fix three oopses in PHY {de,}initialization code
When there are no free snums, UCC ethernet should gracefully fail, but
currently it oopses this way:
# ifconfig eth0 up
fill_init_enet_entries: Can not get SNUM.
ucc_geth_startup: Can not fill p_init_enet_param_shadow.
eth0: Cannot configure net device, aborting.
Unable to handle kernel paging request for data at address 0x00000190
Faulting instruction address: 0xc0294c88
Oops: Kernel access of bad area, sig: 11 [#1]
[...]
NIP [c0294c88] mutex_lock+0x0/0x1c
LR [c01b6be8] phy_stop+0x20/0x70
Call Trace:

[efb25df0] [c020eec0] dev_open+0xc0/0x118
[...]
This is because the ucc_geth_stop() routine assumes that ugeth->phydev
is always initialized by the ucc_geth_open(), while it is not in case
of errors.
If we add a check to the ucc_geth_stop(), then another oops pops up:
Unable to handle kernel paging request for data at address 0x00000004
Faulting instruction address: 0xc01b46a4
Oops: Kernel access of bad area, sig: 11 [#1]
[...]

[ef83bff0] [c000f464] kernel_thread+0x4c/0x68
[...]
That one happens because ucc_geth_stop() does not call phy_disconnect()
and so phylib state machine is running without any idea that a MAC has
just died.
Also, when device tree specifies fixed-link, and CONFIG_FIXED_PHY
is disabled, we'll get this oops:
0:01 not found
eth2: Could not attach to PHY
eth2: Cannot initialize PHY, aborting.
Unable to handle kernel paging request for data at address 0x00000190

[ef82bff0] [c000f464] kernel_thread+0x4c/0x68
[...]
And again, ucc_geth_stop() assumes that ugeth->phydev is there, while
it isn't.
This patch fixes all three oopses simply by rearranging some code:
- In ucc_geth_open(): move init_phy() call to the beginning, so
that we only call ucc_geth_stop() with a PHY attached;
- Move phy_disconnect() call from ucc_geth_close() to
ucc_geth_stop(), so that we'll always disconnect the PHY.

o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,

bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[NET]: Make NAPI polling independent of struct net_device objects.
Several devices have multiple independant RX queues per net
device, and some have a single interrupt doorbell for several
queues.
In either case, it's easier to support layouts like that if the
structure representing the poll is independant from the net
device itself.
The signature of the ->poll() call back goes from:
int foo_poll(struct net_device *dev, int *budget)
to
int foo_poll(struct napi_struct *napi, int budget)
The caller is returned the number of RX packets processed (or
the number of "NAPI credits" consumed if you want to get
abstract). The callee no longer messes around bumping
dev->quota, *budget, etc. because that is all handled in the
caller upon return.
The napi_struct is to be embedded in the device driver private data
structures.
Furthermore, it is the driver's responsibility to disable all NAPI
instances in it's ->stop() device close handler. Since the
napi_struct is privatized into the driver's private data structures,
only the driver knows how to get at all of the napi_struct instances
it may have per-device.
With lots of help and suggestions from Rusty Russell, Roland Dreier,
Michael Chan, Jeff Garzik, and Jamal Hadi Salim.
Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra,
Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan.

[NET]: Make NAPI polling independent of struct net_device objects.
Several devices have multiple independant RX queues per net
device, and some have a single interrupt doorbell for several
queues.
In either case, it's easier to support layouts like that if the
structure representing the poll is independant from the net
device itself.
The signature of the ->poll() call back goes from:
int foo_poll(struct net_device *dev, int *budget)
to
int foo_poll(struct napi_struct *napi, int budget)
The caller is returned the number of RX packets processed (or
the number of "NAPI credits" consumed if you want to get
abstract). The callee no longer messes around bumping
dev->quota, *budget, etc. because that is all handled in the
caller upon return.
The napi_struct is to be embedded in the device driver private data
structures.
Furthermore, it is the driver's responsibility to disable all NAPI
instances in it's ->stop() device close handler. Since the
napi_struct is privatized into the driver's private data structures,
only the driver knows how to get at all of the napi_struct instances
it may have per-device.
With lots of help and suggestions from Rusty Russell, Roland Dreier,
Michael Chan, Jeff Garzik, and Jamal Hadi Salim.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

[NET]: Make NAPI polling independent of struct net_device objects.
Several devices have multiple independant RX queues per net
device, and some have a single interrupt doorbell for several
queues.
In either case, it's easier to support layouts like that if the
structure representing the poll is independant from the net
device itself.
The signature of the ->poll() call back goes from:
int foo_poll(struct net_device *dev, int *budget)
to
int foo_poll(struct napi_struct *napi, int budget)
The caller is returned the number of RX packets processed (or
the number of "NAPI credits" consumed if you want to get
abstract). The callee no longer messes around bumping
dev->quota, *budget, etc. because that is all handled in the
caller upon return.
The napi_struct is to be embedded in the device driver private data
structures.
Furthermore, it is the driver's responsibility to disable all NAPI
instances in it's ->stop() device close handler. Since the
napi_struct is privatized into the driver's private data structures,
only the driver knows how to get at all of the napi_struct instances
it may have per-device.
With lots of help and suggestions from Rusty Russell, Roland Dreier,
Michael Chan, Jeff Garzik, and Jamal Hadi Salim.
Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra,
Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan.
[ Ported to current tree and all drivers converted. Integrated
Stephen's follow-on kerneldoc additions, and restored poll_list
handling to the old style to fix mutual exclusion issues. -DaveM ]

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.
