The code walks all the acpi _CRS methods to see how many windows
to allocate. It then scans them all again to insert_resource()
for each *even if the first scan found that there were none*.
Move the second scan inside the "if (windows)" clause.

This patch should fix TOC handling for cdroms that can not play audio. It
extends commit af744e3294d09d706c4eae26cffaaa68a8d40337 ("cdrom: don't
check CDC_PLAY_AUDIO in cdrom_count_tracks()") with a safety check and
non-audio ioctls support.
Since CDC_PLAY_AUDIO flag was used not only to check ability to play audio
but also to ensure that audio_ioctl was not NULL, all TOC-related
operations had to use it.
As far as I understand, now audio_ioctl is never NULL, so a sanity check
during device registration should be sufficient.
It was tested on Optiarc AD7203A device, that has no ability to play
audio.

The DEFINE macro defines the per_cpu variable as well as the early
map and pointer. It also initializes the per_cpu variable and map
elements to "_initvalue". The early_* macros provide access to
the initial map (usually setup during system init) and the early
pointer. This pointer is initialized to point to the early map
but is then NULL'ed when the actual per_cpu areas are setup. After
that the per_cpu variable is the correct access to the variable.
As these variables are NULL'ed before __init sections are dropped
(in setup_per_cpu_maps), they can be safely annotated as __ref.

x86: correct register constraints for 64-bit atomic operations
x86_64 add/sub atomic ops does not seems to accept integer values bigger
than 32 bits as immediates. Intel's add/sub documentation specifies they
have to be passed as registers.
The only operations in the x86-64 architecture which accept arbitrary
64-bit immediates is "movq" to any register; similarly, the only
operation which accept arbitrary 64-bit displacement is "movabs" to or
from al/ax/eax/rax.
e
32-bit signed integer constant, or a symbolic reference known to fit
that range (for immediate operands in sign-extending x86-64
instructions).
Z
32-bit unsigned integer constant, or a symbolic reference known to
fit that range (for immediate operands in zero-extending x86-64
instructions).
Since add/sub does sign extension, using the "e" constraint seems appropriate.
It applies to 2.6.27-rc, 2.6.26, 2.6.25...

Fix header export of videodev2.h, ivtv.h, ivtvfb.h
The exported copy of videodev2.h contains this line:
#define #include <sys/time.h>
This is because for some reason it defines __user for itself -- despite
the fact that we remove all instances of __user when exporting headers.
_All_ pointers in userspace are user pointers. Fix it by removing the
unnecessary '#define __user' from the file.
The new headers ivtv.h and ivtvfb.h would have the same problem... if
whoever put them there had actually remembered to add them to the Kbuild
file while he was at it. Fix those too, and export them as was
presumably intended.
Note that includes of <linux/compiler.h> are also stripped by the header
export process, so those don't need to be conditional.

With gcc 4.3 and later, a pointer that has already been dereferenced is
assumed not to be null since it should have caused a segmentation fault
otherwise, hence any subsequent test against NULL is optimized away.
Current inline asm constraint used in the implementation of prefetch()
makes gcc believe that the pointer is dereferenced even though the PLD
instruction does not load any data and does not cause a segmentation
fault on null pointers, which causes all sorts of interesting results
when reaching the end of a linked lists for example.
Let's use a better constraint to properly represent the actual usage of

poll_idle was added to CPUIDLE, just as a low latency idle handler, to be
used in cases when user desires CPUs not to enter any idle state at all. It
was supposed to be a run time idle=poll option to the user. But, it was indeed
getting used during normal menu and ladder governor default case, with no

Change below ensures that poll_idle will not be used unless user explicitly

spi: bugfix spi_add_device() with duplicate chipselects
When reviewing a recent patch I noticed a potential trouble spot in the
registration of new SPI devices. The SPI master driver is told to set
the device up before adding it to the driver model, so that it's always
properly set up when probe() is called. (This is important, because in
the case of inverted chipselects, this device can make the bus misbehave
until it's properly deselected. It's got to be set up even if no driver
binds to the device.)
The trouble spot is that it doesn't first verify that no other device
has been added using that chipselect. If such a device has been added,
its configuration gets trashed. (Fortunately this has not been a common
error!)
The fix here adds an explicit check, and a mutex to protect the relevant
critical region.
