[git pull 00/14] Input updates for 2.6.15

[Dmitry Torokhov]

Hi Linus,

Please consider pulling from:

	master.kernel.org:/pub/scm/linux/kernel/git/dtor/input.git

It corrects couple of problems caused by recein input dynalloc
conversion, converts uinput driver to dynamic allocation and
adds new wistron button driver which was siting in -mm for quite
a while.

Vojtech, please bless the pull.

Changelog:

 Fix missing initialization in ir-kbd-gpio.c
 Fix an OOPS when initializing IR remote on saa7134
 Input: make serio and gameport more swsusp friendly
 Input: handle failures in input_register_device()
 Input: uinput - don't use "interruptible" in FF code
 Input: uinput - add UI_SET_SWBIT ioctl
 Input: uinput - convert to dynalloc allocation
 Input: wistron - disable wifi/bluetooth on suspend
 Input: wistron - add PM support
 Input: wistron - convert to dynamic input_dev allocation
 Input: wistron - add support for Acer Aspire 1500 notebooks
 Input: wistron - disable for x86_64
 Input: add Wistron driver
 Input: atkbd - speed up setting leds/repeat state

[git pull 01/14] atkbd - speed up setting leds/repeat state

[Dmitry Torokhov]

[-- Attachment #1: atkbd-led-handling.patch --]
[-- Type: text/plain, Size: 5097 bytes --]

Input: atkbd - speed up setting leds/repeat state

Changing led state is pretty slow operation; when there are multiple
requests coming at a high rate they may interfere with normal typing.
Try optimize (skip) changing hardware state when multiple requests
are coming back-to-back.

[git pull 02/14] Add Wistron driver

[Dmitry Torokhov]

[-- Attachment #1: wistron_buttons.patch --]
[-- Type: text/plain, Size: 13077 bytes --]

Input: add Wistron driver

A driver for laptop buttons using an x86 BIOS interface that is
apparently used on quite a few laptops and seems to be originating
from Wistron.

This driver currently "knows" only about Fujitsu-Siemens Amilo Pro V2000
(i.e. it can detect the laptop using DMI and it contains the
keycode->key meaning mapping for this laptop) and Xeron SonicPro X 155G
(probably can't be reliably autodetected, requires a module parameter),
adding other laptops should be easy.

In addition to reporting button presses to the input layer the driver
also allows enabling/disabling the embedded wireless NIC (using the
"Wifi" button); this is done using the same BIOS interface, so it seems
only logical to keep the implementation together.  Any flexibility
possibly gained by allowing users to remap the function of the "Wifi"
button is IMHO not worth it when weighted against the necessity to run
an user-space daemon to convert button presses to wifi state changes.

[git pull 04/14] Wistron - add support for Acer Aspire notebooks

[Dmitry Torokhov]

[-- Attachment #1: wistron-buttons-acer-aspire-support.patch --]
[-- Type: text/plain, Size: 5176 bytes --]

From: Bernhard Rosenkraenzer <bero@arklinux.org>

Input: wistron - add support for Acer Aspire 1500 notebooks

Also fix a potential issue with some notebooks:

The current code assumes the response to bios_wifi_get_default_setting is
either 1 (disabled) or 3 (enabled), or wifi isn't supported.  The BIOS
response appears to be a bit field w/ 0x1 indicating hardware presence, 0x2
indicating actiation status, and the other 6 bits being unknown/reserved --
with the patch, these 6 bits are ignored.

All these new ioctl's and no compat layer for 32 bits apps on 64 bits
kernels ...

I'll send a patch later today for the current ones, but please, do it
from day #1 next time :)

Ok, forget my promise, I won't do a compat layer for it today. Way too
much crap in there, read's of structs made of other structs & unions
etc... all of this would need compat versions etc... no time for that.

Couldn't you have designed that properly in the first place ?

Oh,and ... ARGH !

So you pass that nice structure 

struct input_event {
	struct timeval time;
	__u16 type;
	__u16 code;
	__s32 value;
};

to userland via read() ... cool, a structure that is not compatible
between 32 and 64 bits passed around via a read call. that will be fun
to fix.

It would need the same treatment as evdev got. Entire uinput is not
32/64 bit friendly (hostorically). However, it should be used by an
userspace "driver", not an ordinary program, so we probably shoudl
just require using native-sized binary with uinput.

Not realistic. Some distros still don't have 64 bits userland ...

[git pull 10/14] Uinput: dont use "interruptible" in FF code

[Dmitry Torokhov]

[-- Attachment #1: uinput-dont-use-wait-completion-interruptible.patch --]
[-- Type: text/plain, Size: 1475 bytes --]

Input: uinput - don't use "interruptible" in FF code

If thread that submitted FF request gets interrupted somehow it
will release request structure and ioctl handler will work with
freed memory. TO prevent that from happening switch to using
wait_for_completion instead of wait_for_completion_interruptible.

[git pull 12/14] Input - help swsusp

[Dmitry Torokhov]

[-- Attachment #1: input-help-swsusp.patch --]
[-- Type: text/plain, Size: 2705 bytes --]

Input: make serio and gameport more swsusp friendly

kseriod and kgameportd used to process all pending events before
checking for freeze condition. This may cause swsusp to time out
while stopping tasks when resuming. Switch to process events one
by one to check freeze status more often.

Linus, please hold off the pull - I messed up authorship of Wistron
driver in commit history plus there is another fix for cinergyT2 driver.

I will redo the tree...

Oh, ok.. Hopefully Miloslav will forgive me.

That cinergyT2 fix (from Linux-2.6.15-rc2 thread) - do you already have it

The only one I have is the one I got through davem a couple of days ago: 

  cinergyT2: cinergyt2_register_rc() should return 0 on success

is that the one you're talking about?
