Convert from ->media_changed() to ->check_events().
DAC960 media change notification seems to be one way (once set, never
cleared) and will generate spurious events when polled once the
condition triggers.

Convert paride drivers from ->media_changed() to ->check_events().
pcd and pd buffer and clear events after reporting; however, pf
unconditionally reports MEDIA_CHANGE and will generate spurious events
when polled.

Convert gdrom and viocd from ->media_changed() to ->check_events().
It's unclear how the conditions are cleared and it's possible that it
may generate spurious events when polled.

Convert the floppy drivers from ->media_changed() to ->check_events().
Both floppy and ataflop buffer media changed state bit and clear them
on revalidation and will behave correctly with kernel event polling.
I can't tell how amiflop clears its event and it's possible that it
may generate spurious events when polled.

Convert ->media_changed() to the new ->check_events() method. The
conversion is mostly mechanical. The only notable change is that
cdrom now doesn't generate any event if @slot_nr isn't CDSL_CURRENT.
It used to return -EINVAL which would be treated as media changed. As
media changer isn't supported anyway, this doesn't make any
difference.
This makes ide emit the standard disk events and allows kernel event
polling. Currently, only MEDIA_CHANGE event is implemented. Adding
support for EJECT_REQUEST shouldn't be difficult; however, given that
ide driver is already deprecated, it probably is best to leave it
alone.

This merge creates two set of conflicts. One is simple context
conflicts caused by removal of throtl_scheduled_delayed_work() in
for-linus and removal of throtl_shutdown_timer_wq() in
for-2.6.39/core.
The other is caused by commit 255bb490c8 (block: blk-flush shouldn't
call directly into q->request_fn() __blk_run_queue()) in for-linus
crashing with FLUSH reimplementation in for-2.6.39/core. The conflict
isn't trivial but the resolution is straight-forward.
* __blk_run_queue() calls in flush_end_io() and flush_data_end_io()
should be called with @force_kblockd set to %true.
* elv_insert() in blk_kick_flush() should use
%ELEVATOR_INSERT_REQUEUE.
Both changes are to avoid invoking ->request_fn() directly from
request completion path and closely match the changes in the commit
255bb490c8.

blk_cleanup_queue()
Now we initialize ->queue_lock at queue allocation time so driver does
not have to worry about initializing it before calling
blk_cleanup_queue().

Convert the SuperH clocks framework and shared interrupt handling
code to using struct syscore_ops instead of a sysdev classes and
sysdevs for power managment.
This reduces the code size significantly and simplifies it. The
optimizations causing things not to be restored after creating a
hibernation image are removed, but they might lead to undesirable
effects during resume from hibernation (e.g. the clocks would be left
as the boot kernel set them, which might be not the same way as the
hibernated kernel had seen them before the hibernation).
This also is necessary for removing sysdevs from the kernel entirely
in the future.

Prevent read urbs from being resubmitted from tasklet after port close.
The receive tasklet was not disabled on port close, which could lead to
corruption of receive lists on consecutive port open. In particular,
read urbs could be re-submitted before port open, added to free list in
open, and then added a second time to the free list in the completion
handler.

In the WDM class driver a disconnect event leads to calls to
usb_free_coherent to put back two USB DMA buffers allocated earlier.
The call to usb_free_coherent uses a different size parameter
(desc->wMaxCommand) than the corresponding call to usb_alloc_coherent
(desc->bMaxPacketSize0).
When a disconnect event occurs, this leads to 'bad dma' complaints
from usb core because the USB DMA buffer is being pushed back to the
'buffer-2048' pool from which it has not been allocated.
This patch against the most recent linux-2.6 kernel ensures that the
parameters used by usb_alloc_coherent & usb_free_coherent calls in
cdc-wdm.c match.

The modularization of the Blackfin driver set the name to "musb-blackfin"
in all the boards, but "musb-bfin" in the driver itself. Since the driver
file name uses "blackfin", change the driver to "musb-blackfin". This is
also easier as it's only one file to change.

This patch (as1453) fixes a long-standing bug in the ehci-hcd driver.
There is no need to set the Halt bit in the overlay region for an
unlinked or blocked QH. Contrary to what the comment says, setting
the Halt bit does not cause the QH to be patched later; that decision
(made in qh_refresh()) depends only on whether the QH is currently
pointing to a valid qTD. Likewise, setting the Halt bit does not
prevent completions from activating the QH while it is "stopped"; they
are prevented by the fact that qh_completions() temporarily changes
qh->qh_state to QH_STATE_COMPLETING.
On the other hand, there are circumstances in which the QH will be
reactivated _without_ being patched; this happens after an URB beyond
the head of the queue is unlinked. Setting the Halt bit will then
cause the hardware to see the QH with both the Active and Halt bits
set, an invalid combination that will prevent the queue from
advancing and may even crash some controllers.
Apparently the only reason this hasn't been reported before is that
unlinking URBs from the middle of a running queue is quite uncommon.
However Test 17, recently added to the usbtest driver, does exactly
this, and it confirms the presence of the bug.
In short, there is no reason to set the Halt bit for an unlinked or
blocked QH, and there is a very good reason not to set it. Therefore
the code that sets it is removed.

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).

The hdpvr's IR part, in short, sucks. As observed with a usb traffic

Its still not behaving as well as I'd like even with this change, but

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.

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.

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.

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
ref-counting nightmare.
