HUT 1.12 defines Logoff usage 0x19c in Consumer page. There are
keyboards out there emitting this usage code (for example Microsoft
Wireless Laser Keyboard 6000). Add this key so that HID code could
map usages to it.

This patch fixes the problem, that Japanese MacBook doesn't recognize some keys
like '\'(yen, or backslash), '|'(pipe), and '_'(underscore).
It is due to that MacBook JIS keyboard (jp106) sends wrong report descriptor.
It saids "logical maximum = 0x65", so Keyboard.0089 is mapped to Key.Unknown,
while it should be accepted as Key.Yen.

The infrared remote receiver found in the SantaRosa MacBookPro
laptops (MacBookPro3,1) need to be forced to expose a HIDDEV
interface (instead of HIDINPUT) so that lirc can access it using
the 'macmini' driver.
The patch below adds the required quirk for forcing the HIDDEV
interface to be activated (HID_QUIRK_HIDDEV) and introduces a new
quirk which forces the HIDINPUT interface to be ignored
(HID_QUIRK_IGNORE_HIDINPUT).
Note that Apple calls this receiver 'IRController4' (info taken
from Apple's driver Info.plist). Older Mac{Book,Mini,Pro}s seem
to all use the 'IRController1' device (USB id 05ac:8240) which
doesn't need those quirks.

Current HID layer does not report usage codes to the input layer. This feature
was previously removed, because it caused unnecessary storm of events in cases
of positioning devices, etc.
This patch adds reporting of usage codes as EV_MSC events only for key events.
We issue the EV_MSC event only if the state of the key corresponding to the
given code has changed, so that we don't report usages that are sent in every
report even if the state hasn't changed (for example Shift/Caps Lock/...
states as sent by various keyboards).
This functionality is required at least by KeyTouch in order to provide
convenient means for remapping the usage codes.

We have to ignore all non-LED usages in output fields if the
report descriptor of the device specifies any. If we don't do
so, the devices which contain the same usages both in input and
output reports with different parameters will mess things up. In
hid-input, we currently care only for the input usages, with exception
for LEDs. All other output usages should be properly handled by
appropriate force-feedback driver.

This keyboard emits a few usages that are not handled properly by
hid-input.
The usages from MSVENDOR page are colliding with Chicony Tactical
Pad device, so we have to distinguish in runtime. Ugly ...
Also, the buttons 1-5 have to be handled in a non-standard way,
as they are emitted by the keyboard in a bitfield-like fashion, but
the field is not presented as bit-field by the keyboard. The keys can't
be pressed simultaneously, so the handling we have is correct.
This patch also extends hid_keyboard[] with KPLeftParenthesis and
KPRightParenthesis as defined by Keyboard page in HUT 1.12. The
corresponding usages are also emitted by this keyboard.

When the UBI device is nearly full, i.e. all LEBs are mapped, we have
only one spare LEB left - the one we reserved for WL purposes. Well,
I do not count the LEBs which were reserved for bad PEB handling -
suppose NOR flash for simplicity. If an "atomic LEB change operation"
is run, and the WL unit is moving a LEB, we have no spare LEBs to
finish the operation and fail, which is not good. Moreover, if there
are 2 or more simultanious "atomic LEB change" requests, only one of
them has chances to succeed, the other will fail with -ENOSPC. Not
good either.
This patch does 2 things:
1. Reserves one PEB for the "atomic LEB change" operation.
2. Serealize the operations so that only on of them may run
at a time (by means of a mutex).

Similar reason as in case of the previous patch: it causes
deadlocks if a filesystem with writeback support works on top
of UBI. So pre-allocate needed buffers when attaching MTD device.
We also need mutexes to protect the buffers, but they do not
cause much contantion because they are used in recovery, torture,
and WL copy routines, which are called seldom.

Use GFP_NOFS flag when allocating memory on I/O path, because otherwise
we may deadlock the filesystem which works on top of us. We observed
the deadlocks with UBIFS. Example:
VFS->FS lock a lock->UBI->kmalloc()->VFS writeback->FS locks the same
lock again.

I can't find anything guaranteeing that 'ubi_num' cannot be <0 in
drivers/mtd/ubi/kapi.c::ubi_open_volume(), and in fact the code
even tests for that and errors out if so. Unfortunately the test
for "ubi_num < 0" happens after we've already used 'ubi_num' as
an array index - bad thing to do if it is negative.
This patch moves the test earlier in the function and then moves
the indexing using that variable after the check. A bit safer :-)

The bank switching code assumes that the bank selector is set to 0
when the driver is loaded. This might not be the case. This is exactly
the same bug as was fixed in the w83627ehf driver two months ago:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0956895aa6f8dc6a33210967252fd7787652537d
In practice, this bug was causing the sensor thermal types to be
improperly reported for my W83627THF the first time I was loading the
w83627hf driver. From the driver history, I'd say that it has been
broken since September 2005 (when we stopped resetting the chip by
default at driver load.)

This patch is to add an abort function that will bring back the MCP51/55
controller if it was blocked by a block-read operation, in particular.
(When a slave sends a wrong byte count on a byte read, the host gets
locked up). I've only tested it on an MCP51 and MCP55. However, I'm
almost certain it will also work on MCP65, I just did not have the board
to test it on. Thus for now the abort function will only be called
if an MCP51/55 was detected.

This is the first part of the patch that adds a function to reset the
nvidia MCP51/55 i2c controller, if something bad happens to it (e.g.
a slave sends a wrong byte count during a block transaction).
This patch just adds nforce2_check_status function. It was originally
written by Hans-Frieder Vogt.
The reason that I'm the one sending it is:
- I relied on it for the second part of the patch,
- It makes the driver code cleaner/better.

Fix a "mis-used register" problem on the AMD MIPS Alchemy au1550
I2C interface.
In summary, the programmable serial controller seems to hang the kernel
when I send a single 'address' byte on the I2C bus. The patch
essentially uses the PSC_SMBSTAT register's TE (transmit FIFO empty)
bit to check when the transmit FIFO is empty, instead of using the
PSC_SMBEVNT register's TU (transmit underflow) bit. Using the TE bit
fixed the hang problem.

This removes:
- An effectively unused hook: i2c_algorithm.algo_control.
- The i2c_control() call, used only by i2c-dev to call that
unused hook or set two barely supported adapter params.
(That param setting moves into i2c-dev.c ... still iffy
due to lack of locking, but no other changes.)
As shown by diffstat, this is a net code shrink. It also reduces the
complexity of the I2C adapter and /dev interfaces.

The I2C_M_RECV_LEN calling convention for i2c_mesg.flags involves
