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
the pointer value.

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
special user setting (Reported by Linus Torvalds).

Change below ensures that poll_idle will not be used unless user explicitly
asks pm_qos infrastructure for zero latency requirement.

Pardo reported that 64-bit threaded apps, if their stacks exceed the
combined size of ~4GB, slow down drastically in pthread_create() - because
glibc uses MAP_32BIT to allocate the stacks. The use of MAP_32BIT is
a legacy hack - to speed up context switching on certain early model
64-bit P4 CPUs.

So introduce a new flag to be used by glibc instead, to not constrain
64-bit apps like this.

glibc can switch to this new flag straight away - it will be ignored
by the kernel. If those old CPUs ever matter to anyone, support for
it can be implemented.

Jean Delvare's machine triggered this BUG

acpi_os_map_memory phys ffff0000 size 65535
------------[ cut here ]------------
kernel BUG at arch/x86/mm/pat.c:233!

with ACPI in the backtrace.

Adding some debugging output showed that ACPI calls

acpi_os_map_memory phys ffff0000 size 65535

And ioremap/PAT does this check in 32bit, so addr+size wraps and the BUG
in reserve_memtype() triggers incorrectly.

        BUG_ON(start >= end); /* end is exclusive */

But reserve_memtype already uses u64:

int reserve_memtype(u64 start, u64 end,

so the 32bit truncation must happen in the caller. Presumably in ioremap
when it passes this information to reserve_memtype().

This patch does this computation in 64bit.

Testing with a modified fsfuzzer reveals a couple of locations in omfs
where filesystem variables are ultimately used as loop counters with
insufficient sanity checking.  In this case, dir->i_size is used to
compute the number of buckets in the directory hash.  If too large,
readdir will overrun a buffer.

Since it's an invariant that dir->i_size is equal to the sysblock
size, and we already sanity check that, just use that value instead.

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.

write_cache_pages() uses i_mapping->writeback_index to pick up where it
left off the last time a given inode was found by pdflush or
balance_dirty_pages (or anyone else who sets wbc->range_cyclic)

alloc_inode() should set it to a sane value so that writeback doesn't
start in the middle of a file.  It is somewhat difficult to notice the bug
since write_cache_pages will loop around to the start of the file and the
elevator helps hide the resulting seeks.

For whatever reason, Btrfs hits this often.  Unpatched, untarring 30

for them, and don't cache the results so that we always get the latest
