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.

Also, exported symbol hid_resolv_event is unused by the current

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 :-)

All the users go through virt_irq_to_bucket() and essentially
want to go from a virt_irq to an INO, but we have a way
to do that already via virt_to_real_irq_table[].dev_ino.
This also allows us to kill both virt_to_real_irq() and
virt_irq_to_bucket().

We were simply concatenating the devhandle and devino and using that
as the cookie, which defeats the entire purpose of the VIRQ hypervisor
interfaces.
Now that we use physical addresses for the INO buckets, we can
allocate them dynamically for VIRQs and encode the cookies as
~__pa(bucket). This allows us to test for and decode the cookie with
a simple:
brlz $reg1, 1f
xnor $reg1, %g0, $reg2
sequence.
This works because bit 64 is never set in traditional
INO vectors, and it is also never set in a physical
address. So xnor'ing the physical address of the bucket
always gives us a negative number, and thus a unique
condition we can test cheaply.
Inspired by ideas from Greg Onufer.

Currently we chain IVEC entries using 32-bit "pointers"
because we know that the ivector_table is in the main
kernel image, thus below 4GB.
This uses proper 64-bit pointers instead.
Whilst this bloats up the kernel image size, this sets
the infrastructure necessary to significantly shrink the
kernel size by using physical addresses and dynamically
allocating the ivector table.

This also makes us use the MSI queues correctly.
Each MSI queue is serviced by a normal sun4u/sun4v INO interrupt
handler. This handler runs the MSI queue and dispatches the
virtual interrupts indicated by arriving MSIs in that MSI queue.
All of the common logic is placed in pci_msi.c, with callbacks to
handle the PCI controller specific aspects of the operations.
This common infrastructure will make it much easier to add MSG
support.

Thanks to Tom Callaway for the excellent bug report and
test case.
sys_ipc() has several problems, most to due with semaphore
call handling:
1) 'err' return should be a 'long'
2) "union semun" is passed in a register on 64-bit compared
to 32-bit which provides it on the stack and therefore
by reference
3) Second and third arguments to SEMCTL are swapped compared
to 32-bit.

The name field of of_platform_driver is just copied into the
included device_driver. By not overriding an already initialised
device_driver name, we can convert the drivers over time to stop using
the of_platform_driver name.
Also we were not copying the owner field from of_platform_driver, so do
the same with it.

Added asm-sparc/irqflags.h and moved irq related code from system.h to it.
Renamed local_irq functions to raw_local_irq in irq.c.
Modified system.h to include linux/irqflags.h which includes asm/irqflags.h.
Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug.
This is the first step in adding IRQ-flags state tracing as outlined in
Documentation/irqflags-tracing.txt. These changes should be harmless
because they just move things around and rename them.
The next step is making the lowlevel entry code modifications which
to be honest are beyond my capabilities at this point.
