Following the suggestion of Jonas, this patch maps the special keys of
the MS Presenter 8000 to targets that should allow for better re-mapping
according to individual use cases (i.e. I avoided hard-wiring to
standard keys). This time I also included the last missing key event
(switching back from presentation mode).

The optimal Xmodmap customization for using the Presenter with
OpenOffice now looks like this for me:

keycode 175 = Escape
keycode 179 = F5
keysym XF86Forward = Right
keysym XF86Back = Left

Samsung USB remotes (0419:0001) are rejected by kernel 2.6.23, because the
report descriptor from the remote contains a 48 bit HID report field. HID 1.11
states: Fields may span at most 4 bytes.

This patch, based on 2.6.23, fixes this by modifying the internal report
descriptor in hid-quirks.c. Additional user space support (e.g. LIRC) is
required to fetch the information from the hiddev interface.

The burden to reconstruct the data is moved into userspace (lirc through hiddev).
There is no need to set HID_QUIRK_HIDDEV quirk, as the device has also output
applications, which trigger the creation of hiddev device automatically.

The device is not discoverable, and needs to be poked to set its master, the
Bluetooth device it will try to connect to when the "Home" button is pressed
without a cable plugged in.

Using libusb means disconnecting the device from its driver to get the report
descriptor. Using hiddev, we can poke it without relinquishing control over it,
so when you plug it in, it would still work as a pad.

This could be then used by sixpair program, after it is rewritten to use
hiddev instead of libusb.

smc91x is shared between many different platforms.  Each platform needs
to specify the interrupt type, and in some cases the irq type depends
on more than just the build configuration - it depends on runtime
checks.

Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide
a way for these flags to be passed via the IRQ resource itself.

Note that IRQF_TRIGGER_* constants are intentionally defined to correspond
with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that
the low bits of PCI iomem resources correspond with the BAR flag bits.

Also provide a way to configure smc91x to read the IRQ flags from the
resource.  Once all platforms have been converted over (signified
by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should
be removed.

This patch converts xsysace to use blk_end_request interfaces.
Related 'uptodate' arguments are converted to 'error'.

xsysace is a little bit different from "normal" drivers.
xsysace driver has a state machine in it.
It calls end_that_request_first() and end_that_request_last()
from different states. (ACE_FSM_STATE_REQ_TRANSFER and
ACE_FSM_STATE_REQ_COMPLETE, respectively.)

However, those states are consecutive and without any interruption
inbetween.
So we can just follow the standard conversion rule (b) mentioned in
the patch subject "[PATCH 01/30] blk_end_request: add new request

This patch converts ide-cd (cdrom_newpc_intr()) to use blk_end_request
interfaces.  Related 'uptodate' arguments are converted to 'error'.

In PIO mode, ide-cd (cdrom_newpc_intr()) needs to defer
end_that_request_last() until the device clears DRQ_STAT and raises
an interrupt after end_that_request_first().
So blk_end_request() has to return without completing request
even if no leftover in the request.

ide-cd uses blk_end_request_callback() and a dummy callback function,
which just returns value '1', to tell blk_end_request_callback()
about that.

This patch converts "normal" parts of ide to use blk_end_request
interfaces.  Related 'uptodate' arguments are converted to 'error'.

The conversion of 'uptodate' to 'error' is done only for the internal
function, __ide_end_request().
ide_end_request() was not changed since it's exported and used
by many ide drivers.

With this patch, blkdev_dequeue_request() in __ide_end_request() is
moved to blk_end_request, since blk_end_request takes care of
dequeueing request like below:

	if (!list_empty(&rq->queuelist))
		blkdev_dequeue_request(rq);

In the case of ide,
  o 'dequeue' variable of __ide_end_request() is 1 only when the request
    is still linked to the queue (i.e. rq->queuelist is not empty)
  o 'dequeue' variable of __ide_end_request() is 0 only when the request
    has already been removed from the queue (i.e. rq->queuelist is empty)
So blk_end_request can handle it correctly although ide always run
thought the code above.
