This driver uses an app-specific keymap for one of the tables. This
is wrong. Instead, use the standard keycodes.

Using xev and testing the "Windows" key on a normal keyboard, it
is mapped as KEY_LEFTMETA. So, as this is the standard code for
it, use it, instead of a generic, meaningless KEY_PROG1.

Those KEY_PROG[n] keys were used on places where the developer
didn't know for sure what key should be used. On several cases,
using KEY_RED, KEY_GREEN, KEY_YELLOW would be enough. On others,
there are specific keys for that already.

Each keyboard map were using a different definition for
the Source/Video Source key.
Behold Columbus were the only one using KEY_PROPS.
As we want to standardize those keys at X11 and at
userspace applications, we need to use just one code
for it.

Update the TODO.lirc_zilog based on what has been completed. Also revised
the development plan for lirc_zilog to not try and split Tx/Rx for one IR
transceiver unit between lirc_zilog and ir-kbd-i2c, since that would be a

This is a major change to add pointer reference counting for
struct IR, struct IR_tx, and struct IR_rx object instances.
This ref counting gets lirc_zilog closer to gracefully handling
bridge drivers and hot-unplugged USB devices disappearing out from
under lirc_zilog when the /dev/lircN node is still open. (mutexes
to protect the i2c_client pointers in struct IR_tx and struct IR_rx
still need to be added.)
This reference counting also helps lirc_zilog clean up properly
when the i2c_clients disappear.

Always allocate a lirc_buffer object, instead of just upon setup of
the Rx i2c_client. If we do not allocate a lirc_buffer object, because
we are not handling the Rx i2c_client, lirc_dev will allocate its own
lirc_buffer anyway and not tell us about its location.

There is no need to take the rx->buf_lock in the the poll() function
as all the underling calls made on objects in the rx->buf lirc_buffer object
are protected by spinlocks.
Corrected a bad error return value in poll(): return POLLERR instead
of -ENODEV.
Added some comments to poll() for when, in the future, I forget what
poll() and poll_wait() are supposed to do.

The open count is simply used for deciding if the Rx polling thread
needs to poll the IR chip for userspace. Simplify the manipulation
of the open count by using an atomic_t and not requiring a lock

The set_use_inc() and set_use_dec() functions tried to lock
the underlying bridge driver device instance in memory by
changing the use count on the device's i2c_clients. This
worked for PCI devices (ivtv, cx18, bttv). It doesn't
work for hot-pluggable usb devices (pvrusb2 and hdpvr).
With usb device instances, the driver may get locked into
memory, but the unplugged hardware is gone.
The set_use_inc() set_use_dec() functions also tried to have
lirc_zilog change its own module refernce count, which is
racy and not guaranteed to work. The lirc_dev module does
actually perform proper module ref count manipulation on the
lirc_zilog module, so there is need for lirc_zilog to
attempt a buggy module get on itself anyway.
lirc_zilog also errantly called these functions on itself
in open() and close(), but lirc_dev did that already too.
So let's just gut the bodies of the set_use_*() functions,
and remove the extra calls to them from within lirc_zilog.
Proper reference counting of the struct IR, IR_rx, and IR_tx
objects -- to handle the case when the underlying
bttv, ivtv, cx18, hdpvr, or pvrusb2 bridge driver module or
device instance goes away -- will be added in subsequent
patches.

Recent zerocopy work in the 9P VirtIO transport maps and pins
user buffers into kernel memory for the server to work on them.
Since the user process can initiate this kind of pinning with a simple
read/write call, thousands of IO threads initiated by the user process can
hog the system resources and could result into denial of service.
This patch introduces flow control to avoid that extreme scenario.
The ceiling limit to avoid denial of service attacks is set to relatively
high (nr_free_pagecache_pages()/4) so that it won't interfere with
regular usage, but can step in extreme cases to limit the total system
hang. Since we don't have a global structure to accommodate this variable,
I choose the virtio_chan as the home for this.

Given that the sprious wake-ups are common, we need to move the
condition setting right next to the wake_up(). After setting the condition
to req->status = REQ_STATUS_RCVD, sprious wakeups may cause the
virtqueue back on the free list for someone else to use.
This may result in kernel panic while relasing the pinned pages
in p9_release_req_pages().
Also rearranged the while loop in req_done() for better redability.

Process may wait to get space on VirtIO ring to send a transaction to
VirtFS server. Current code just does a conditional wake_up() which
means only one process will be woken up even if multiple processes
are waiting.
This fix makes the wake_up unconditional. Hence we won't have any
processes waiting for-ever.

Lina reported that if throttle limits are initially very high and then
dropped, then no new bio might be dispatched for a long time. And the
reason being that after dropping the limits we don't reset the existing
slice and do the rate calculation with new low rate and account the bios
dispatched at high rate. To fix it, reset the slice upon rate change.
https://lkml.org/lkml/2011/3/10/298
Another problem with very high limit is that we never queued the
bio on throtl service tree. That means we kept on extending the
group slice but never trimmed it. Fix that also by regulary
trimming the slice even if bio is not being queued up.

convert vmtruncate usage to truncate_setsize. We also writeback
all dirty pages before doing 9p operations and on success call truncate_setsize.
This ensure that we continue sanely on failed truncate on the server. The
disadvantage is that we are now going to write back the content that get
thrown away later as a part of truncate.

This is a second version of an rc-core based driver for the ITE Tech IT8712F
CIR and now for a pair of other variants of the IT8512 CIR too.
This driver should replace the lirc_it87 and lirc_ite8709 currently living in
the LIRC staging directory.
The driver should support the ITE8704, ITE8713, ITE8708 and ITE8709 (this last
one yet untested) PNP ID's.
The code doesn'te reuse code from the pre-existing LIRC drivers, but has been
written from scratch using the nuvoton.cir driver as a skeleton.
This new driver shouldn't exhibit timing problems when running under load (or
with interrupts disabled for relatively long times). It works OOTB with the
RC6 MCE remote bundled with the ASUS EEEBox. TX support is implemented, but
I'm unable to test it since my hardware lacks TX capability.

As the code in saa7134-input is not a module, but the config for it is
set as a boolean instead of a tristate, this causes a strange dependency
on RC_CORE.
VIDEO_SAA7134_RC (which determines if saa7134-input.o is built) depends
on RC_CORE and VIDEO_SAA7134. If VIDEO_SAA7134 is compiled as 'y' but
RC_CORE is compiled as 'm' VIDEO_SAA7134_RC can still be set to 'y'
which causes undefined symbols that it needs from RC_CORE.
The simplest solution is to not allow VIDEO_SAA7134_RC be enabled if
RC_CORE compiled as a module (m) and VIDEO_SA7134 is compiled into the
kernel (y).

This patch fixes a bug in gspca, more precisely in alt_xfer().
This function looks for an input transfer endpoint in an alternate setting.
By default it returns the first endpoint corresponding to the transfer type
indicated in parameter.
But with some USB devices, the first endpoint corresponding to the transfer
type is not always an INPUT endpoint but an OUTPUT one.
This patch adds the endpoint direction test to be sure to return an INPUT endpoint
