This patch allows tweaking the behaviour of GPIO_STATUS register
shift quirk that's in wm97xx-core. The problem with GPIO_STATUS
register being shifted by one doesn't appear on all hardware it
seems and causes problems with accelerated touchscreen drivers on
Palm hardware. Therefore an accelerated touchscreen driver can select
if the shift is/isn't happening on the hardware.

Commit 3d5cb60e ("Input: simplify name handling for certain input
handles") introduced a regression for the EVIOCGNAME/JSIOCGNAME
ioctl.
Before this, patch, the platform device's name was given back to
userspace which was good to identify devices. After this patch, the
device is ("event%d", minor) which is not descriptive at all.
This fixes the behaviour by taking dev->name.

This patch adds DMI information to automatically load the correct

are clones of Fujitsu Amilo V2000, the hook for the v2000 is being
used and I have tested that perfectly works.
The immediate result of integrating this patch is that the five
special buttons will work on these specific notebook models and that
the RF killswitch will not be activated after suspend. This patch
definitively obsoletes the fsam7400 module which I was still needing
to enable wifi and to fix the RF killswitch suspend problem; in the
current 2.6.30 kernel it is necessary to load the wistron_btns module
with options 'force=1 keymap=1557/MS2141', which was not anyway a

Original patch by Marek Vasut, modified by Eric in:
1. use delayed work to simplify the debouncing
2. combine col_polarity/row_polarity into a single active_low field
3. use a generic bit array based XOR algorithm to detect key
press/release, which should make the column assertion time
shorter and code a bit cleaner
4. remove the ALT_FN handling, which is no way generic, the ALT_FN
key should be treated as no different from other keys, and
translation will be done by user space by commands like 'loadkeys'.
5. explicitly disable row IRQs and flush potential pending work,
and schedule an immediate scan after resuming as suggested
by Uli Luckas
6. incorporate review comments from many others
Patch tested on Littleton/PXA310 (though PXA310 has a dedicate keypad
controller, I have to configure those pins as generic GPIO to use this
driver, works quite well, though), and Sharp Zaurus model SL-C7x0
and SL-C1000.

PIT_TICK_RATE is currently defined in four architectures, but in three
different places. While linux/timex.h is not the perfect place for it, it
is still a reasonable replacement for those drivers that traditionally use
asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency.
Note that for Alpha, the actual value changed from 1193182UL to 1193180UL.
This is unlikely to make a difference, and probably can only improve
accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE
a few years ago, after which every existing instance was getting changed

I found the PrimeCell/AMBA Bus drivers distrusting the resource
passed in as part of the struct amba_device abstraction. This
patch removes all hard coded resource sizes found in the PrimeCell
drivers and move the responsibility of this definition back to
the platform/board device definition, which already exist and
appear to be correct for all in-tree users of these drivers.
We do this using the resource_size() inline function which was
also replicated in the only driver using the resource size, so
that has been changed too. The KMI_SIZE was left in kmi.h in case
someone likes it. Test-compiled against Versatile and Integrator
defconfigs, seems to work but I don't posess these boards and
cannot test them.

reading first X and then Y coordinates. When coordinate data is ready

The appletouch driver is prone to reporting multiple fingers when only
one is pressing. The appletouch driver queries an array of pressure
sensors and counts local maxima in pressure to determine the number of
fingers. It just does this on the raw values, so a data stream like:
0 100 250 300 299 300 250 100 0
actually registers as 2 fingers.

When userspace sets effect->u.rumble.strong_magnitude to 0x8001 or
larger, ml_combine_effects() would always return strong_magnitude
0xffff.
Problem is that 'gain' is passed in as signed integer. Multiplying
magnitude (__u16) with gain (int) causes magnitude read as signed and
results negative value (with magnitude > 0x8000). This signed integer
is then divided and value, still negative, converted to 32bit unsigned
integer. Finally checking combine overflow min(new+old, 0xffff) gives
out 0xffff.
Fix is to simply change 'gain' to unsigned int.

dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

In order to utilize the full power of the new multi-touch devices, a
way to report detailed finger data to user space is needed. This patch
adds a multi-touch (MT) protocol which allows drivers to report details
for an arbitrary number of fingers.
The driver sends a SYN_MT_REPORT event via the input_mt_sync() function
when a complete finger has been reported.
In order to stay compatible with existing applications, the data
reported in a finger packet must not be recognized as single-touch
events. In addition, all finger data must bypass input filtering,
since subsequent events of the same type refer to different fingers.
A set of ABS_MT events with the desired properties are defined. The
events are divided into categories, to allow for partial implementation.
The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and
ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked.
If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide
the size of the approaching finger. Anisotropy and direction may be
specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and
ABS_MT_ORIENTATION. Devices with more granular information may specify
general shapes as blobs, i.e., as a sequence of rectangular shapes
grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE
may be used to specify whether the touching tool is a finger or a pen.

Simple input driver support for the events reported by the
MSP430 firmware on the DM355 EVM. Verified using the RC5
remote included with the kit; docs weren't quite right.
Some of the keycode selections might need improvement; they
can be remapped, so there's at least a runtime workaround.
(I also suspect Linux may someday merit more generic support
for RC5 based remote controls.)
These events don't distinguish key press vs release events,
so this reports both and then skips the next event if it's
identical. The RC5 remote codes include a "toggle" bit that
can help detect autorepeated keys; but this driver doesn't
bother with those nuances.
This driver relies on the drivers/mfd/dm355evm_msp.c code
for core features, including sharing I2C access to this
firmware with GPIO, LED, and RTC support.

Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
as correctly noted at bug #12454. Someone can lookup entry with NULL
->owner, thus not pinning enything, and release it later resulting
in module refcount underflow.
We can keep ->owner and supply it at registration time like ->proc_fops
and ->data.
But this leaves ->owner as easy-manipulative field (just one C assignment)
and somebody will forget to unpin previous/pin current module when
switching ->owner. ->proc_fops is declared as "const" which should give
some thoughts.
->read_proc/->write_proc were just fixed to not require ->owner for
protection.
rmmod'ed directories will be empty and return "." and ".." -- no harm.
And directories with tricky enough readdir and lookup shouldn't be modular.
We definitely don't want such modular code.
Removing ->owner will also make PDE smaller.
So, let's nuke it.

Most fasync implementations do something like:

But fasync_helper() will return a positive value at times - a feature used

err = fasync_helper(...);
if (err < 0)

Mikrotik's Routerboard 532 has two builtin buttons, from which one
triggers a hardware reset. The other one is accessible through GPIO
pin 1. Sadly, this pin is being multiplexed with UART0 input, so
enabling it as interrupt source (as implied by the gpio-keys driver)
is not possible unless UART0 has been turned off. The later one though
is a rather bad idea as the Routerboard is an embedded device with
only a single serial port, so it's almost always used as serial
console device.
This patch adds a driver based on INPUT_POLLDEV, which disables the
UART and reconfigures GPIO pin 1 temporarily while reading the button
state. This procedure works fine and has been tested as part of
another, unpublished driver for this device.

When resuming from suspend newer Synaptics touchpads do not recover
correctly. Analysis of the resume sequence as applied in Linux was
compared to that of other operating systems. This indicated that the
other OSs were resetting the mouse before attempting to detect it (for
all Synaptics touchpads, old and new). Applying this same modification
fixes these newer Synaptics touchpads and brings the driver into line
with common OS reset behaviour.

Commit ec42d4481e broke usbtouchscreen for

Devices confirmed to be real HID have the class set to HID and the protocol
set to 'mouse'. Some have HID class but protocol set to 'none'. Those are
not HID and should be driven by usbtouchscreen.
Fix the device ignoring macro by adding match for the protocol too.

This patch updates the maple bus to support asynchronous block reads
and writes as well as generally improving the quality of the code and
supporting concurrency (all needed to support the Dreamcast visual
memory unit - a driver will also be posted for that).
Changes in the bus driver necessitate some changes in the two maple bus
input drivers that are currently in mainline.
As well as supporting block reads and writes this code clean up removes
some poor handling of locks, uses an atomic status variable to serialise
access to devices and more robusly handles the general performance
problems of the bus.

Whenever you press and then release a key, the CPU wakes up
three times:
* press
* release
* autorepeat timer exactly 250ms after press
The autorepeat timer has nothing to do, obviously, since you already
have released the key, so stop it on key release.
[dtor@mail.ru: This changes autorepeat behavior a bit since we now stop
autorepeat even if key that is being released is not the one that is
being auto-repeated, but I believe the new behavior is better.]

Impact: cleanup, move all hrtimer processing into hardirq context
This is an attempt at removing some of the hrtimer complexity by
reducing the number of callback modes to 1.
This means that all hrtimer callback functions will be ran from HARD-irq
context.
I went through all the 30 odd hrtimer callback functions in the kernel
and saw only one that I'm not quite sure of, which is the one in
net/can/bcm.c - hence I'm CC-ing the folks responsible for that code.
Furthermore, the hrtimer core now calls callbacks directly with IRQs
disabled in case you try to enqueue an expired timer. If this timer is a
periodic timer (which should use hrtimer_forward() to advance its time)
then it might be possible to end up in an inf. recursive loop due to the
fact that hrtimer_forward() doesn't round up to the next timer
granularity, and therefore keeps on calling the callback - obviously
this needs a fix.
Aside from that, this seems to compile and actually boot on my dual core
test box - although I'm sure there are some bugs in, me not hitting any
makes me certain :-)

The usbtouchscreen module implements a driver for the TSC-10 DM USB
touchscreen controllers, but assumes a 2-byte response for the
CMD_RESET and CMD_RATE commands, when they can be only a single byte
when no EEPROM is connected.
The driver worked with an earlier controller revision, but new
revisions of the controller fail.
It seems the problem is that the early controller had the
SEL4/EEPROM-CS pin high, but the new controller has it down, making
the response different.
Without the fix, the controller would answer the single byte 0x06
(ACK), making the init fail with -ENODEV because buf[1] is 0xFF (as
initialized before).
As the single byte is the only thing we need to check it was ok, there
is no need to verify the second byte.
The [0x15 0x01] case is the NAK [0x15] response for when there is no
data in the EEPROM [bit-0 of second byte set], so I let that be, as I
don't have any controller with an EEPROM.
With this patch, both the earlier and latest controller work the same.
Note: This was previously submited as BUG #11961 [1] on the bugzilla

The appletouch driver has grown up from supporting only a couple of
touchpads into supporting many touchpads, which can have different
number of sensors, different aspect ratios etc.
This patch cleans up the current driver code and makes it easy to
support the features of each different touchpad.
As a side effect, this patch also modifies the 'Y' multiplication factor
of the 'geyser3' and 'geyser4' touchpads (found on Core Duo and Core2
Duo MacBook and MacBook Pro laptops) in order to make the touchpad
output match the aspect ratio of the touchpad (Y factor changed from 43
to 64).

This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.
This is all fairly brainless/obvious stuff. Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads. (That would improve
with hardware IRQ debouncing enabled, of course...)

The problem of finger tracking, i.e., when to switch focus from one
finger to another on the trackpad, has been improved by utilizing more
information from the bcm5974 chip output. This results in less pointer
hopping when many fingers are on the trackpad. In addition, a finger
counting method based on pressure information from all fingers is
introduced. Together with a pressure hysteresis window, this yields a
more stable counting of the number of fingers on the trackpad.

Currently the support for each WM97xx touchscreen model is compiled out
by default, meaning that the default configuration when the driver is

The pvfb backend indicates dynamic mode support by creating node
feature_resize with a non-zero value in its xenstore directory.
xen-fbfront sends a resize notification event on mode change. Fully
backwards compatible both ways.
Framebuffer size and initial resolution can be controlled through
kernel parameter xen_fbfront.video. The backend enforces a separate
size limit, which it advertises in node videoram in its xenstore
directory.
xen-kbdfront gets the maximum screen resolution from nodes width and
height in the backend's xenstore directory instead of hardcoding it.
Additional goodie: support for larger framebuffers (512M on a 64-bit
system with 4K pages).
Changing the number of bits per pixels dynamically is not supported,
yet.

This is a pair of Xen para-virtual frontend device drivers:

drivers/input/xen-kbdfront provides keyboard and mouse.
The backends run in dom0 user space.
The two drivers are not in two separate patches, because the
intermediate step (one driver, not the other) is somewhat problematic:
the backend in dom0 needs both drivers, and will refuse to complete
device initialization unless they're both present.

For devices not specifically listed in xpad.c, xpad->dpad_mapping
is initially set to MAP_DPAD_UNKNOWN. In xpad_probe() it gets changed
to either MAP_DPAD_TO_BUTTONS or MAP_DPAD_TO_AXES, depending on the
module parameter dpad_to_buttons.
However, MAP_DPAD_UNKNOWN is defined as -1, while the field is u8.
This results in actual value of 255, causing the MAP_DPAD_UNKNOWN
check in xpad_probe() to fail.
Fix that by defining MAP_DPAD_UNKNOWN as 2 instead.
Also, setting module parameter dpad_to_buttons to 1 should obviously
map dpad to buttons, while the default behaviour (0) should be to map
dpad to axes. However, dpad_to_buttons is directly assigned to
xpad->dpad_mapping, and as MAP_DPAD_TO_BUTTONS is 0, the actual
behaviour is reversed.
Fix that by negating dpad_to_buttons in assignment.

I/O memory range), and make it possible to remove those registers
definition in pxa-regs.h as PXA is undergoing a clean-up of that
header file
2. use device specific IRQ instead of hardcoded IRQ_KEYPAD, same

3. clean up the error handling path in _probe()

as the legacy code does or as any specified key code, this is
useful on some platform which uses the rotary keys as
KEY_{UP/DOWN/LEFT/RIGHT}

2. Use KEY() macro to define matrix keys, instead of original 8x8 map
this makes definition easier with keypad where keys are sparse
3. Keep a generated array in "struct pxa27x_keypad" for fast lookup

This patch adds a very simple input power event to APM user suspend
event bridge. Its currently only works for the systems using the
emulated APM driver but could easily be extended to work with anything
with a true APM BIOS too.
This covers a standard embedded system need which is to suspend when the
user presses a suspend button. It leaves options open to system
integrators to ignore (or unload) this code and implement their own more
complex event handling system.
Its hidden behind the EMBEDDED Kconfig option since its only likely to
be of use to embedded style systems. It can be built as a module so the
"hardcoded" policy can easily be removed from the kernel at runtime if
desired too.

local symbol 1: discarded in section `.devexit.text' from drivers/built-in.o
(The error message above is from kbuild.git but it happens in mainline too)
The error happens becase there is a reference from .text/.data to a
function marked __devexit. With CONFIG_HOTPLUG=n all code marked
__devexit are discarded and the linker complains.
It was tracked down to sparcspkr.c which were missing __devexit_p()

This driver supports the application buttons on some Fujitsu Lifebook
laptops. It is based on the earlier apanel driver done by Jochen Eisenger,
but with many changes. The original driver used ioctl's and a separate
user space program (see http://apanel.sourceforge.net). This driver hooks
into the input subsystem so that the normal keys act as expected without a
daemon. In addition to buttons, the Mail Led is handled via LEDs class
device.
The driver now supports redefinable keymaps and no longer has to have a DMI
table for all Fujitsu laptops.
I thought about mixing this driver should be integrated into the Fujitsu
laptop extras driver that handles backlight, but rejected the idea because
it wasn't clear if all the Fujitsu laptops supported both.

Devices like the HP Integrated Remote Console Virtual Mouse, which are
standard equipment on all Proliant and Integrity servers, produce
absolute coordinates instead of relative coordinates. This is done to
synchronize the position of the mouse cursor on the client desktop
with the mouse cursor position on the server. Mousedev is not
designed to pass those absolute events directly to X, but it can
translate them into relative movements. It currently does this for
tablet like devices and touchpads. This patch merely tells it to also
include a device with ABS_X, ABS_Y, and mouse buttons in its list of
devices to process input for.

When NR_CPU count is raised to 4096 the size of cpu_data becomes
3,145,728 bytes.
These changes were adopted from the sparc64 (and ia64) code. An
additional field was added to cpuinfo_x86 to be a non-ambiguous cpu
index. This corresponds to the index into a cpumask_t as well as the
per_cpu index. It's used in various places like show_cpuinfo().
cpu_data is defined to be the boot_cpu_data structure for the NON-SMP

This changes the uevent buffer functions to use a struct instead of a

proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

Three main sets of changes:
1) dmi_get_system_info() return value should have been marked const,
since callers should not be changing that data.
2) const-ify DMI internals, since DMI firmware tables should,
whenever possible, be marked const to ensure we never ever write to
that data area.
3) const-ify DMI API, to enable marking tables const where possible
in low-level drivers.
And if we're really lucky, this might enable some additional
optimizations on the part of the compiler.
The bulk of the changes are #2 and #3, which are interrelated. #1 could
have been a separate patch, but it was so small compared to the others,
it was easier to roll it into this changeset.

The appletouch geyser3 devices found in the Intel Macs (and possibly

touch. This results in the kernel waking up around once every couple of
milliseconds to process them, making it almost impossible to spend any
significant amount of time in C3 state on a dynamic HZ kernel. Sending
the mode initialization code makes the device shut up until it's touched
again. This patch does so after receiving 10 packets with no interesting

The ads7846 driver has support for filtering, but when the chip gets
deselected between samples this causes noise. This patch adds support
for an optional settling delay time, so that two consecutive samples
will be taken with the specified delay time apart. This ensures that
the chip won't be deselected, so the noise won't appear.
Filtering can still be done, but will have less work to do since each
time a new sample is taken the same delay applies.

Export LEDs on Xbox360 pad via led subsystem as a single device in
/sys/class/leds/xpad[0-9]+.
Xbox360 pad has four leds, which form a circle. Unfortunately the leds
can't be controlled independently and can only display a predefined
set of patterns (for example one is turned on wile others are off or
a rotating pattern - 1-2-3-4). To activate a pattern one needs to send
a specific command to the device (see http://www.free60.org/wiki/Gamepad).
Led subsystem allows us to set brightness, but there is nothing like
brightness on this device. So brightness is actually interpreted as
the command (only values between 0 and 14 are accepted).

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.
It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.
The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

the keymaps by fitting each entry on an int. Most of the dmi matching was
written based on google searches, so it's rather prone to errors. That's
why I'm asking people to confirm it works.

Pete Zaitcev reports that with his touchpad, if he lifts the finger
and places it elsewhere, the pointer sometimes warps dramatically.
This happens because we don't store coordinates unless we detect a
touch so sometimes we have stale coordinates in queue (from where
the finger left the pad) and averaging makes cursor to jump across
the screen. The solution is to always store the latest coordinates.

Most drivers using GPIOs already know they are running on a system that
supports the generic GPIO calls, because of other platform dependencies.
But the generic GPIO-based LED and input button drivers can't know that.
So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms
where <asm/gpio.h> will do the right thing. Currently that's a bunch of
ARMs, and AVR32; more are on the way.
It also fixes a dependency bug for the gpio button input driver; it was
wrong to start with, now it covers all platforms with GENERIC_GPIO.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all

Clean up several code points in which the return code from misc_register is
not handled properly.
Several modules failed to deregister various hooks when misc_register fails,
and this patch cleans them up. Also there are a few modules that legitimately
don't care about the failure status of misc register. These drivers however
unilaterally call misc_deregister on module unload.
Since misc_register doesn't initialize the list_head in the init_routine if it
fails, the deregister operation is at risk for oopsing when list_del is
called. The initial solution was to manually init the list in the miscdev
structure in each of those modules, but the consensus in this thread was to
consolodate and do that universally inside misc_register.

Pass the work_struct pointer to the work function rather than context data.
The work function can use container_of() to work out the data.
For the cases where the container of the work_struct may go away the moment the
pending bit is cleared, it is made possible to defer the release of the
structure by deferring the clearing of the pending bit.
To make this work, an extra flag is introduced into the management side of the
work_struct. This governs auto-release of the structure upon execution.
Ordinarily, the work queue executor would release the work_struct for further
scheduling or deallocation by clearing the pending bit prior to jumping to the
work function. This means that, unless the driver makes some guarantee itself
that the work_struct won't go away, the work function may not access anything
else in the work_struct or its container lest they be deallocated.. This is a
problem if the auxiliary data is taken away (as done by the last patch).
However, if the pending bit is *not* cleared before jumping to the work
function, then the work function *may* access the work_struct and its container
with no problems. But then the work function must itself release the
work_struct by calling work_release().
In most cases, automatic release is fine, so this is the default. Special
initiators exist for the non-auto-release case (ending in _NAR).

MUX error handling has a workaround for KBCs that get confused which
port data came from and signal MUXERR while data is actually good.
Unfortunately this workaround hurts with KBCs that signal timeouts
as 0xfc (spec says that only 0xfd, 0xfe and 0xff are alowed with
MUXERR) since it causes endless attempts to rescan i8042 serio
ports. The solution is to treat 0xfc as timeout (0xfe).

In mousedev the BTN_LEFT and BTN_FORWARD were mapped to mouse button 0,
causing that the user space program cannot distinguish between them through
/dev/input/mice. All mice have BTN_LEFT, but not all have BTN_MIDDLE (e.g.
Clevo D410J laptop). Mapping BTN_FORWARD to mouse button 2 makes the
BTN_FORWARD button useful on this laptop.

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.

The effects are now file descriptor specific instead of the previous strange
half-process half-fd specific behaviour. The effect memory of devices is not
emptied if the root user opens and closes the device while another user is
using effects. This is a minor change and most likely no force feedback
