V4L/DVB: IR/streamzap: functional in-kernel decoding
This patch makes in-kernel decoding with the stock Streamzap PC Remote
work out of the box. There are quite a few things going on in this
patch, all related to getting this working:
1) I had to enable reporting of a long space at the end of each signal,
or I had weird buffering and keybounce issues.
2) The keymap has been reworked slightly to match actual decoded values,
the first edition was missing the pre-data bits present in the lirc
config file for this remote.
3) There's a whole new decoder included, specifically for the
not-quite-RC5 15-bit protocol variant used by the Streamzap PC
Remote. The decoder, while usable with other recievers (tested with
an mceusb receiver), will only be loaded by the streamzap driver, as
its likely not of use in almost all other situations. This can be
revisited if/when all keytable loading (and disabling of unneeded
protocol decoder engines) is moved to userspace, but for now, I think
this makes the most sense.
Note that I did try to enable handling the streamzap RC5-ish protocol in
the current RC5 decoder, but there's no particularly easy way to tell if
its 14-bit RC5 or 15-bit Streamzap until we see bit 14, and even then,
in testing an attempted decoder merge, only 2/3 of the keys were
properly recognized as being the 15-bit variant and decoded correctly,
the rest were close enough to compliant with 14-bit that they were
decoded as such (but they have overlap with one another, and thus we
can't just shrug and use the 14-bit decoded values).
Also of note in this patch is the removal of the streamzap driver's
internal delay buffer. Per discussion w/Christoph, it shouldn't be
needed by lirc any longer anyway, and it doesn't seem to make any
difference to the in-kernel decoder engine. That being the case, I'm
yanking it all out, as it greatly simplifies the driver code.

The old usbvideo ibmcam driver needs to be replaced with a v4l2 driver

framework.
This new gspca sub driver sets a first step in that direction. The ibmcam
driver supports 4 different model webcams. This new driver (for now) only
supports Model 3 cameras, as my test cam is a Model 3 cam, or so I thought.
Upon reading:
http://www.linux-usb.org/ibmcam/
I learned that the IBM Netcamera Pro I have even though having the same
usb id and the same bcd version is different from the Model 3 cameras
supported by the ibmcam driver. So this new gscpa subdriver supports Model 3
cameras (untested), and the IBM Netcamera Pro. Currently use with the
IBM Netcamera Pro requires a module parameter. I hope to be able to
autodetect which is which in the future.

virtio: console: Don't block entire guest if host doesn't read data
If the host is slow in reading data or doesn't read data at all,
blocking write calls not only blocked the program that called write()
but the entire guest itself.
To overcome this, let's not block till the host signals it has given
back the virtio ring element we passed it. Instead, send the buffer to
the host and return to userspace. This operation then becomes similar
to how non-blocking writes work, so let's use the existing code for this
path as well.
This code change also ensures blocking write calls do get blocked if
there's not enough room in the virtio ring as well as they don't return
-EAGAIN to userspace.

For i.MX21 we keep the current behaviour, that is calling

i2c-imx: do not allow interruptions when waiting for I2C to complete
The i2c_imx_trx_complete() function is using
wait_event_interruptible_timeout() to wait for the I2C controller to
signal that it has completed an I2C bus operation. If the process that
causes the I2C operation receives a signal, the wait will be
interrupted, returning an error. It is better to let the I2C operation
finished before handling the signal (i.e. returning into userspace).
It is safe to use wait_event_timeout() instead, because the timeout
will allow the process to exit if the I2C bus hangs. It's also better
to allow the I2C operation to finish, because unacknowledged I2C
operations can cause the I2C bus to hang.

firewire: ohci: fix TI TSB82AA2 regression since 2.6.35
Revert commit
54672386ccf36ffa21d1de8e75624af83f9b0eeb
"firewire: ohci: fix up configuration of TI chips".
It caused massive slow-down and data corruption with a TSB82AA2 based
StarTech
EC1394B2 ExpressCard and FireWire 800 harddisks.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/657081
http://thread.gmane.org/gmane.linux.kernel.firewire.user/4013
The fact that some card EEPROMs do not program these enhancements may be
related to TSB81BA3 phy chip errata, if not to bugs of TSB82AA2 itself.
We could re-add these configuration steps, but only conditional on a
whitelist of cards on which these enhancements bring a proven positive
effect.

ALSA: rawmidi: fix oops (use after free) when unloading a driver module
When a driver module is unloaded and the last still open file is a raw
MIDI device, the card and its devices will be actually freed in the
snd_card_file_remove() call when that file is closed. Afterwards, rmidi
and rmidi->card point into freed memory, so the module pointer is likely
to be garbage.

"Sorry, reordering breakage. In the signals tree here I have
static inline void sig_set_blocked(struct sigset_t *set)

and it's used all over the place (including quite a few places where
we currently have sigprocmask(SIG_SETMASK, set, NULL), which is what
it's equivalent to). With that done, m32r doesn't use _BLOCKABLE

v4l1: fix 32-bit compat microcode loading translation
The compat code for the VIDIOCSMICROCODE ioctl is totally buggered.
It's only used by the VIDEO_STRADIS driver, and that one is scheduled to
staging and eventually removed unless somebody steps up to maintain it
(at which point it should use request_firmware() rather than some magic
ioctl). So we'll get rid of it eventually.
But in the meantime, the compatibility ioctl code is broken, and this
tries to get it to at least limp along (even if Mauro suggested just
deleting it entirely, which may be the right thing to do - I don't think
the compatibility translation code has ever worked unless you were very
lucky).

De-pessimize rds_page_copy_user
Don't try to "optimize" rds_page_copy_user() by using kmap_atomic() and
the unsafe atomic user mode accessor functions. It's actually slower
than the straightforward code on any reasonable modern CPU.
Back when the code was written (although probably not by the time it was
actually merged, though), 32-bit x86 may have been the dominant
architecture. And there kmap_atomic() can be a lot faster than kmap()
(unless you have very good locality, in which case the virtual address
caching by kmap() can overcome all the downsides).
But these days, x86-64 may not be more populous, but it's getting there
(and if you care about performance, it's definitely already there -
you'd have upgraded your CPU's already in the last few years). And on
x86-64, the non-kmap_atomic() version is faster, simply because the code
is simpler and doesn't have the "re-try page fault" case.
People with old hardware are not likely to care about RDS anyway, and
the optimization for the 32-bit case is simply buggy, since it doesn't
verify the user addresses properly.

mmc: sdio: fix SDIO suspend/resume regression
Fix SDIO suspend/resume regression introduced by
4c2ef25fe0b "mmc: fix
all hangs related to mmc/sd card insert/removal during suspend/resume":
PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.01 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
Suspending console(s) (use no_console_suspend to debug)
pm_op(): platform_pm_suspend+0x0/0x5c returns -38
PM: Device pxa2xx-mci.0 failed to suspend: error -38
PM: Some devices failed to suspend
4c2ef25fe0b moved the card removal/insertion mechanism out of MMC's
suspend/resume path and into pm notifiers (mmc_pm_notify), and that
broke SDIO's expectation that mmc_suspend_host() will remove the card,
and squash the error, in case -ENOSYS is returned from the bus suspend
handler (mmc_sdio_suspend() in this case).
mmc_sdio_suspend() is using this whenever at least one of the card's SDIO
function drivers does not have suspend/resume handlers - in that case
it is agreed to force removal of the entire card.
This patch fixes this regression by trivially bringing back that part of
mmc_suspend_host(), which was removed by
4c2ef25fe0b.

ubd: fix incorrect sector handling during request restart
Commit
f81f2f7c (ubd: drop unnecessary rq->sector manipulation)
dropped request->sector manipulation in preparation for global request
handling cleanup; unfortunately, it incorrectly assumed that the
updated sector wasn't being used.
ubd tries to issue as many requests as possible to io_thread. When
issuing fails due to memory pressure or other reasons, the device is
put on the restart list and issuing stops. On IO completion, devices
on the restart list are scanned and IO issuing is restarted.
ubd issues IOs sg-by-sg and issuing can be stopped in the middle of a
request, so each device on the restart queue needs to remember where
to restart in its current request. ubd needs to keep track of the
issue position itself because,
* blk_rq_pos(req) is now updated by the block layer to keep track of
_completion_ position.
* Multiple io_req's for the current request may be in flight, so it's
difficult to tell where blk_rq_pos(req) currently is.
Add ubd->rq_pos to keep track of the issue position and use it to
correctly restart io_req issue.

Un-inline the core-dump helper functions

0eead9ab41da ("Don't dump task struct in a.out core-dumps") broke the
ia64 compile due to missing the necessary header file includes.
Rather than add yet another include (<asm/unistd.h>) to make everything
happy, just uninline the silly core dump helper functions and move the
bodies to fs/exec.c where they make a lot more sense.
dump_seek() in particular was too big to be an inline function anyway,
and none of them are in any way performance-critical. And we really
don't need to mess up our include file headers more than they already
are.
