The osprey eeprom routine wasn't run for the 440, add it. It was also crap,
re-written to be better.
Add the Osprey 440 to the Bt878 ALSA driver's whitelist. Currently the sample
rate is fixed at 32kHz, as the driver doesn't support different rates for
digital input mode, though the card can select the rate from 32, 44.1, or 48
kHz via gpio.
Setting the audio gain via ALSA isn't supported yet; a userspace tool that
programs the X9221 via i2c-dev must be used.
The Bt878 digital audio format isn't programmed correctly for the CS5331A ADC
used, resulting in extremely garbled sound. That is fixed in a followup
patch.

When raw capture was turned off, the current capturing frame (v4l_grab_frame)

would think this frame was currently being captured, and wait for it to
complete before starting a new frame. The hardware on the other hand would
not be actively capturing a frame. The result was the driver would wait
forever for v4l_grab_frame to be captured.
Some calls to zr36057_set_memgrab(0) were missing spin-locks, which have been
added.

image. For example, a 192x128 YUYV image is 49152 bytes but the driver would
always return 131072 bytes since if that was the size of the v4l buffer.

During uncompressed capture, the poll() function was looking the wrong frame.
It was using the frame the driver was going to capture into next (pend_tail),
when it should have been looking at the next frame to be de-queued with
DQBUF/SYNC (sync_tail).
It also wasn't looking in the right spot. It was looking at the file handle's
copy of the buffer status, rather than the driver core copy. The interrupt
routine marks frames as done in the driver core copy, the file handle copy
isn't updated. So even if poll() looked at the right frame, it would never
see it transition to done and return POLLIN.
The compressed capture code has this same problem, looking in fh->jpg_buffers
when it should have used zr->jpg_buffers.
There was some logic to detect when there was no current capture in process
nor any frames queued and try to return an error, which ends up being a bad
idea. It's possible to call select() from one thread while no capture is in
process, or no frames queued, and then start a capture or queue frames from
another thread.
The buffer state variables are protected by a spin lock, which the code wasn't
acquiring. That is fixed too.

V4L/DVB (5886): zr36067: Fix problem setting norms
The zr36067 driver doesn't make a distinction between the different sub-types
of NTSC, PAL, or SECAM norms. For example, when the enum std ioctl returns
the PAL standard it returns PAL_BG|PAL_DK|PAL_H|PAL_I.
When setting the norm, it required the bitmask to match exactly the set of
norms used during the enumeration. If just one norm was specified, for
example PAL_BG or NTSC_M, it would fail. This violates the V4L2 spec,
"VIDIOC_S_STD accepts *one* or more flags..."
The key thing to realize is that V4L2_STD_PAL is not one bit, it is multiple
bits. It's ok to call S_STD with any *one* of those bits, but the driver was
requiring *all* of them.
This fixes the S_STD function so that it will accept any set of one or more
PAL norms as PAL, and the same for NTSC and SECAM.

Make lguest compile with CONFIG_BLOCK=n and CONFIG_NET=n
Gabriel C reports lguest doesn't compile with CONFIG_BLOCK=n. Fix this
by introducing a config var for the block device, which depends on
LGUEST && BLOCK. Do the same for the net driver, rather then depending
gratuitously on CONFIG_NET.

Remove fs.h from mm.h. For this,
1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
2) Add back fs.h or less bloated headers (err.h) to files that need it.
As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
rebuilt down to 3444 (-12.3%).
Cross-compile tested without regressions on my two usual configs and (sigh):

ACPI: restore CONFIG_ACPI_SLEEP

Introduce CONFIG_SUSPEND for suspend-to-Ram and standby
Introduce CONFIG_SUSPEND representing the ability to enter system sleep
states, such as the ACPI S3 state, and allow the user to choose SUSPEND
and HIBERNATION independently of each other.
Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
been chosen and the kernel is intended for SMP systems.
Also, introduce CONFIG_PM_SLEEP which is automatically selected if
CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
code needed for both suspend and hibernation.
The top-level power management headers and the ACPI code related to
suspend and hibernation are modified to use the new definitions (the
changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
the number of ifdefs).
There are many other files in which CONFIG_PM can be replaced with
CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
the future.

Provide timespec to guests rather than jiffies clock.
A non-periodic clock_event_device and the "jiffies" clock don't mix well:
tick_handle_periodic() can go into an infinite loop.
Currently lguest guests use the jiffies clock when the TSC is
unusable. Instead, make the Host write the current time into the lguest
page on every interrupt. This doesn't cost much but is more precise
and at least as accurate as the jiffies clock. It also gets rid of
the GET_WALLCLOCK hypercall.
Also, delay setting sched_clock until our clock is set up, otherwise
the early printk timestamps can go backwards (not harmful, just ugly).

Fix lguest bzImage loading with CONFIG_RELOCATABLE=y
Jason Yeh sent his crashing .config: bzImages made with
CONFIG_RELOCATABLE=y put the relocs where the BSS is expected, and we
crash with unusual results such as:
lguest: unhandled trap 14 at 0xc0122ae1 (0xa9)
Relying on BSS being zero was merely laziness on my part, and
unfortunately, lguest doesn't go through the normal startup path (which
does this in asm).
