V4L/DVB: v4l: Add driver for Samsung S5P SoC video postprocessor
This driver exports a video device node per each camera interface/
video postprocessor (FIMC) device contained in Samsung S5P SoC series.
The driver is based on v4l2-mem2mem framework.

V4L/DVB: uvcvideo: Drop corrupted compressed frames
Corrupted video frames are dropped by default by the driver for
uncompressed formats. Data corruption is not less problematic for
compressed formats, so frame drop should be enabled by default for those
formats as well.
Mark buffers as faulty when an isochronous packet loss is detected for
any format, or when the buffer length doesn't match the image size for
uncompressed formats. Drop erroneous buffers regardless of whether the
format is compressed or uncompressed.

V4L/DVB: IR keymap: Add print button for HP OEM version of MCE remote
This patch adds a defintion for the "Print" button found on HP OEM
versions of the MCE remote. All of the other keys found on the HP OEM
version of the remote match the other keys as already defined.
Because, who doesn't need "remote printing", while one is sitting on the
couch across from one's PC? ;)

V4L/DVB: IR: extend interfaces to support more device settings
LIRC: add new IOCTL that enables learning mode (wide band receiver)
Still missing features: carrier report & timeout reports.
Will need to pack these into ir_raw_event
V4L/DVB: IR: add helper function for hardware with small o/b buffer
Some ir input devices have small buffer, and interrupt the host
each time it is full (or half full)
Add a helper that automaticly handles timeouts, and also
automaticly merges samples of same time (space-space)
Such samples might be placed by hardware because size of
sample in the buffer is small (a byte for example).
Also remove constness from ir_dev_props, because it now contains timeout
settings that driver might want to change
Currently, ir device registration fails if keymap requested by driver is not found.
Fix that by always compiling in the empty keymap, and using it as a failback.
Some handlers (lirc for example) allocates memory on initialization,
doing so in atomic context is cumbersome.
Fixes warning about sleeping function in atomic context.
* lirc: Don't propagate reset event to userspace
* lirc: Remove strange logic from lirc that would make first sample always be pulse
* Make TO_US macro actualy print what it should.

V4L/DVB: staging/lirc: port lirc_streamzap to ir-core
This ports lirc_streamzap.c over to ir-core in-place, to be followed by
a patch moving the driver over to drivers/media/IR/streamzap.c and
enabling the proper Kconfig bits.
Presently, the in-kernel keymap doesn't work, as the stock Streamzap
remote uses an RC-5-like, but not-quite-RC-5 protocol, which the
in-kernel RC-5 decoder doesn't cope with. The remote can be used right
now with the lirc bridge driver though, and other remotes (at least an
RC-6(A) MCE remote) work perfectly with the driver.
I'll take a look at making the existing RC-5 decoder cope with this odd
duck, possibly implement another standalone decoder engine, or just
throw up my hands and say "meh, use lirc"... But the driver itself
should be perfectly sound.
Remaining items on the streamzap TODO list:
- add LIRC_SET_REC_TIMEOUT-alike support
- add LIRC_GET_M{AX,IN}_TIMEOUT-alike support
- add LIRC_GET_REC_RESOLUTION-alike support
All of the above should be trivial to add. There are patches pending to
add this support to ir-core from Maxim Levitsky, and I'll take care of
these once his patches get integrated. None of them are currently
essential though.

V4L/DVB: cx25840: Add support for CX2388[57] A/V core integrated IR controllers
This patch is primarily a port of the integrated IR controller code in
cx23885/cx23888-ir.c. Right now, only the CX2388[57] AV core will
really try to set up IR. This IR support, by design, still requires the
bridge driver to do final IO pin mux configuration and setup of the IR
controller parameters.
For the CX2388[578] chips, enabling the AV Core for IR also starts
sending Audio and Video interrupts to the bridge driver. For
CX2388[578] chips audio and video interrupts are ignored and
acknowledged when they happen.
IR interrupt handling and status logging is exluded for the CX23888
which does not have an IR controller on the AV core.
Note that experimentation reveals that the IR irq enables on the
CX23885 have an inverted logic sense. The CX23887 likely suffers from
the same quirk. For these chips, those irq enable bits are handled
as interrupt disables.

nfsd: don't allow setting maxblksize after svc created
It's harmless to set this after the server is created, but also
ineffective, since the value is only used at the time of
svc_create_pooled(). So fail the attempt, in keeping with the pattern
set by write_versions, write_{lease,grace}time and write_recoverydir.
(This could break userspace that tried to write to nfsd/max_block_size
between setting up sockets and starting the server. However, such code
wouldn't have worked anyway, and I don't know of any examples--rpc.nfsd
in nfs-utils, probably the only user of the interface, doesn't do that.)

nfsd: initialize nfsd versions before creating svc
Commit 59db4a0c102e0de226a3395dbf25ea51bf845937 "nfsd: move more into
nfsd_startup()" inadvertently moved nfsd_versions after
nfsd_create_svc(). On older distributions using an rpc.nfsd that does
not explicitly set the list of nfsd versions, this results in
svc-create_pooled() being called with an empty versions array. The
resulting incomplete initialization leads to a NULL dereference in
svc_process_common() the first time a client accesses the server.
Move nfsd_reset_versions() back before the svc_create_pooled(); this
time, put it closer to the svc_create_pooled() call, to make this
mistake more difficult in the future.
