It works on hardware other than Macbook Pros, and it works on GPUs other
than Nvidia. It should even work on iMacs, so change the name to match
reality more precisely and include an alias so existing users don't get
confused.

This driver only has to deal with two different classes of hardware, but
right now it needs new DMI entries for every new machine. It turns out
that there's an ACPI device that uniquely identifies Apples with backlights,
so this patch reworks the driver into an ACPI one, identifies the hardware
by checking the PCI vendor of the root bridge and strips out all the DMI
code. It also changes the config text to clarify that it works on devices
other than Macbook Pros and GPUs other than nvidia.

list_del() leaves poison in the prev and next pointers. The next
list_empty() will compare those poisons, and say the list isn't empty.
Any list operations that assume the node is on a list because of such a
check will be fooled into dereferencing poison. One needs to INIT the
node after the del, and fortunately there's already a wrapper for that -
list_del_init().
Some of the dels are followed by deallocations, so can be ignored, and one
can be merged with an add to make a move. Apart from that, I erred on the
side of caution in making nodes list_empty()-queriable.

The oom killer naturally defers killing anything if it finds an eligible
task that is already exiting and has yet to detach its ->mm. This avoids
unnecessarily killing tasks when one is already in the exit path and may
free enough memory that the oom killer is no longer needed. This is
detected by PF_EXITING since threads that have already detached its ->mm
are no longer considered at all.
The problem with always deferring when a thread is PF_EXITING, however, is
that it may never actually exit when being traced, specifically if another
task is tracing it with PTRACE_O_TRACEEXIT. The oom killer does not want
to defer in this case since there is no guarantee that thread will ever
exit without intervention.
This patch will now only defer the oom killer when a thread is PF_EXITING
and no ptracer has stopped its progress in the exit path. It also ensures
that a child is sacrificed for the chosen parent only if it has a
different ->mm as the comment implies: this ensures that the thread group
leader is always targeted appropriately.

This patch prevents unnecessary oom kills or kernel panics by reverting
two commits:
495789a5 (oom: make oom_score to per-process value)
cef1d352 (oom: multi threaded process coredump don't make deadlock)
First, 495789a5 (oom: make oom_score to per-process value) ignores the
fact that all threads in a thread group do not necessarily exit at the
same time.
It is imperative that select_bad_process() detect threads that are in the
exit path, specifically those with PF_EXITING set, to prevent needlessly
killing additional tasks. If a process is oom killed and the thread group
leader exits, select_bad_process() cannot detect the other threads that
are PF_EXITING by iterating over only processes. Thus, it currently
chooses another task unnecessarily for oom kill or panics the machine when
nothing else is eligible.
By iterating over threads instead, it is possible to detect threads that
are exiting and nominate them for oom kill so they get access to memory
reserves.
Second, cef1d352 (oom: multi threaded process coredump don't make
deadlock) erroneously avoids making the oom killer a no-op when an
eligible thread other than current isfound to be exiting. We want to
detect this situation so that we may allow that exiting thread time to
exit and free its memory; if it is able to exit on its own, that should
free memory so current is no loner oom. If it is not able to exit on its
own, the oom killer will nominate it for oom kill which, in this case,
only means it will get access to memory reserves.
Without this change, it is easy for the oom killer to unnecessarily target
tasks when all threads of a victim don't exit before the thread group
leader or, in the worst case, panic the machine.

If an administrator tries to swapon a file backed by NFS, the inode mutex is
taken (as it is for any swapfile) but later identified to be a bad swapfile
due to the lack of bmap and tries to cleanup. During cleanup, an attempt is
made to close the file but with inode->i_mutex still held. Closing an NFS
file syncs it which tries to acquire the inode mutex leading to deadlock. If
lockdep is enabled the following appears on the console;
=============================================
[ INFO: possible recursive locking detected ]

but task is already holding lock:

This patch releases the mutex if its held before calling filep_close()
so swapon fails as expected without deadlock when the swapfile is backed
by NFS. If accepted for 2.6.39, it should also be considered a -stable
candidate for 2.6.38 and 2.6.37.

Using delayed-work for tty flip buffers ends up causing us to wait for
the next tick to complete some actions. That's usually not all that
noticeable, but for certain latency-critical workloads it ends up being
totally unacceptable.
As an extreme case of this, passing a token back-and-forth over a pty
will take two ticks per iteration, so even just a thousand iterations
will take 8 seconds assuming a common 250Hz configuration.
Avoiding the whole delayed work issue brings that ping-pong test-case
down to 0.009s on my machine.
In more practical terms, this latency has been a performance problem for
things like dive computer simulators (simulating the serial interface
using the ptys) and for other environments (Alan mentions a CP/M emulator).

The Apple and TiVo remotes I've got use an NEC-ish protocol, but rather
than a command/not_command pair, they have what appear to be vendor ID
bytes. This change makes the NEC decoder warn if the command/not_command
checksum fails, but then passes along a full 32-bit scancode for keymap
lookup. This change should make no difference for existing keymaps,
since they simply won't have 32-bit scancodes, but allows for a 32-bit
keymap. At the moment, that'll have to be uploaded by the user, but I've
got Apple and TiVo remote keymaps forthcoming.
In the long run (2.6.40, hopefully), we should probably just always use
all 32 bits for all NEC keymaps, but this should get us by for 2.6.39.
(Note that a few of the TiVo keys actuallly *do* pass the command
checksum, so for now, the keymap for this remote will have to be a mix
of 24-bit and 32-bit scancodes, but so be it).

This keymap were used for the Hauppauge Black remote controller
only. It also contains some keycodes not found there. As the
Hauppauge Black is now part of the hauppauge keymap, just remove
it.
Also, remove the modprobe hacks to select between the Gray
and the Black versions of the remote controller as:
- Both are supported by default by the keymap;
- If the user just wants one keyboard supported,
it is just a matter of changing the keymap via
the userspace tool (ir-keytable), removing
the keys that he doesn't desire. As ir-keytable
auto-loads the keys via udev, this is better than
obscure modprobe parameters.

The rc-hauppauge-new map is a messy thing, as it bundles 3
different remote controllers as if they were just one,
discarding the address byte. Also, some key maps are wrong.
With the conversion to the new rc-core, it is likely that
most of the devices won't be working properly, as the i2c
driver and the raw decoders are now providing 16 bits for
the remote, instead of just 8.

There are two "hauppauge-new" keymaps, one with protocol
unknown, and the other with the protocol marked accordingly.
However, both tables are miss-named.
Also, the old rc-hauppauge-new is broken, as it mixes
three different controllers as if they were just one.
This patch solves half of the problem by renaming the
correct keycode table as just rc-hauppauge. This table
contains the codes for the four different types of
remote controllers found on Hauppauge cards, properly
mapped with their different addresses.
create mode 100644 drivers/media/rc/keymaps/rc-hauppauge.c
delete mode 100644 drivers/media/rc/keymaps/rc-rc5-hauppauge-new.c

The keys for the old black were messed with the ones for the
hauppauge grey. Fix it.
Also, fixes some keycodes and order the keys according with
the way they appear inside the remote controller.

Hans borrowed me an old Black Hauppauge RC. Thanks to that, we
can fix the RC5 table for Hauppauge.

One of the remotes has a picture available at:
http://lirc.sourceforge.net/remotes/leadtek/Y04G0004.jpg
As there's one variant with a set direction keys plus vol/chann
keys, and the same table is used for both models, change it to
represent all keys, avoiding the usage of weird function keys.
