Calling uname() with the UNAME26 personality set allows a leak of kernel
stack contents. This fixes it by defensively calculating the length of
copy_to_user() call, making the len argument unsigned, and initializing
the stack buffer to zero (now technically unneeded, but hey, overkill).

Pull media fixes from Mauro Carvalho Chehab:
"Media fixes for:
- one Kconfig fix patch;
- one patch fixing DocBook breakage due to the drivers/media UAPI
changes;
- the remaining UAPI media changes (DVB API).
I'm aware that is is a little late for the UAPI renames for the DVB
API, but IMHO, it is better to merge it for 3.7, due to two reasons:
1) There is a major rename at 3.7 (not only uapi changes, but also
the entire media drivers were reorganized on 3.7, in order to
simplify the Kconfig logic, and easy drivers selection, especially
for hybrid devices). By confining all those renames there at 3.7
it will cause all the harm at for media developers on just one
shot. Stable backports upstream and at distros will likely
welcome it as well, as they won't need to check what changed on
3.7 and what was postponed for on 3.8.
2) The V4L2 DocBook Makefile creates a cross-reference between the
media API headers and the specs. This helps us _a_lot_ to be sure
that all API improvements are properly documented. Every time a
header changes from one place to another, DocBook/media/Makefile
needs to be patched. Currently, the DocBook breakage patch
depends on the DVB UAPI."

Commit 38f3865744 ("xattr: extract simple_xattr code from tmpfs") moved
some code from tmpfs but introduced a subtle bug along the way.
If the name passed to simple_xattr_remove() does not exist in the list of
xattrs, then it is possible to call kfree(new_xattr) when new_xattr is
actually initialized to itself on the stack via uninitialized_var().
This causes a BUG() since the memory was not allocated via the slab
allocator and was not bypassed through to the page allocator because it
was too large.
Initialize the local variable to NULL so the kfree() never takes place.

Earlier without cpuidle framework on pseries, the native arch
idle routine comprised of both snooze and nap
states. smt_snooze_delay variable was used to delay
the idle process entry to deeper idle state like nap.
With the coming of cpuidle, this arch specific idle was replaced
by two different idle routines, one for supporting snooze and other
for nap. This enabled addition of more
low level idle states on pseries in the future.
On adopting the generic cpuidle framework for POWER systems,
the decision of which idle state to choose from, given a predicted
idle time is taken by the menu governor based on
target_residency and exit_latency of the idle states.
target_residency is the minimum time to be resident in that idle state.
Exit_latency is time taken to exit out of idle state.
Deeper the idle state, both the target residency and exit latency
would be higher.
In the current design, smt_snooze_delay is used as target_residency
for the snooze state which is incorrect, as it is not the
minimum but the maximum duration to be in snooze state.
This would result in the governor in taking bad decision,
as presently target_residency of nap < target_residency of snooze
inspite of nap being deeper idle state.
This patch aims to fix this problem by replacing the smt_snooze_delay loop
in snooze state, with the need_resched() as the governor is aware of
entry and exit of various idle transitions based on which
next idle time prediction.
The governor is intelligent enough to determine the idle state the needs to
be transitioned to and maintains a whole of heuristics including
io load, previous idle states predictions etc for the same, based on
which idle state entry decision is taken.
With this fix, of setting target_residency of snooze to 0
nap to smt_snooze_delay
if the predicted idle time is less
than smt_snooze_delay (target_residency of nap)
value governor would pick snooze state, else nap. This adhers to the
previous native idle design.

smt_snooze_delay was designed to delay idle loop's nap entry
in the native idle code before it got ported over to use as part of
the cpuidle framework.
A -ve value assigned to smt_snooze_delay should result in
busy looping, in other words disabling the entry to nap state.
- https://lists.ozlabs.org/pipermail/linuxppc-dev/2010-May/082450.html
This particular functionality can be achieved currently by
echo 1 > /sys/devices/system/cpu/cpu*/state1/disable
but it is broken when one assigns -ve value to the smt_snooze_delay
variable either via sysfs entry or ppc64_cpu util.
This patch aims to fix this, by disabling nap state when smt_snooze_delay
variable is set to -ve value.

Remove the redundant target residency initialisation in pseries_cpuidle_driver_init().
This is currently over-writing the residency time updated as part of the static
table, resulting in all the idle states having the same target
residency of 100us which is incorrect. This may result in the menu governor making

"They do a number of things:
(1) Import a patch from Catalin Marinas to extend the generic-y in
Kbuild facility to uapi directories.
(2) Make arch/tile's ucontext.h file use (1) and remove the header-y
line from the kernel internal side of things.
(3) Remove some now-empty conditional bits from include/linux/Kbuild.
The contents got moved to the UAPI side of things along with new
conditionals.
(4) Deal with now-empty files:
(a) Empty Kbuild files under include/ get removed.
(b) Empty Kbuild files under arch/ get comments to hold them as
they are likely to end up with generic-y or genhdr-y lines.
Deleting them appears to work if we want to go that route.
(c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the
patch program from deleting that, and made the arches with
empty kvm_para.h uapi files use that instead of having their
own files.
(d) Put comments into four other empty uapi/ headers to prevent the
patch program from deleting them.
A question: Is this the right way to deal with the now-empty Kbuild
files?
The ones under include/ are unlikely to be used - even for generated
files, I think - so getting rid of them is probably okay. Once all
the bits are in, we can probably remove all the Kbuild files under
include/ that aren't also under include/uapi/.
The ones under arch/ are more of an issue because of the potential for
generic-y and genhdr-y."

At the merge, the dependencies were not done right: the menu

for digital TV. As there are other I2C devices there (flash

to make it generic enough to open for all media devices with

Make uapi/asm-generic/kvm_para.h non-empty by addition of a comment to stop
the patch program from deleting it when it creates it.
Then delete empty arch-specific uapi/asm/kvm_para.h files and tell the Kbuild
files to use the generic instead.
Should this perhaps instead be a #warning or #error that the facility is
unsupported on this arch?

Place comments in:
arch/mips/include/asm/Kbuild
arch/tile/include/arch/Kbuild
to make them non-empty so that the patch program doesn't remove them when it
reduces them to nothing.
Possibly they should be just deleted, but it's possible that they'll acquire
generic-y or genhdr-y lines in future, so I'm keeping them around for the
moment.
Note that MIPS will compile happily if the file is deleted instead. I haven't
tested TILE, but I suspect it will be the same there.

Remove non-UAPI Kbuild files that have become empty as a result of UAPI
disintegration. They used to have only header-y lines in them and those have
now moved to the Kbuild files in the corresponding uapi/ directories.
Possibly these should not be removed but rather have a comment inserted to say
they are intentionally left blank. This would make it easier to add generated
header lines in future without having to restore the infrastructure.
Note that at this point not all the UAPI disintegration parts have been merged,
so it is likely that more empty Kbuild files will turn up.
It is probably necessary to make the files non-empty to prevent the patch
program from automatically deleting them when it reduces them to nothing.

uapi/linux/irqnr.h was emitted by the UAPI disintegration script as an empty
file because the parent linux/irqnr.h had no UAPI stuff in it, despite being
marked with "header-y".
Unfortunately, the patch program deletes the empty file when applying a kernel
patch.
It's not clear why this file is part of the UAPI at all. Looking in:
/usr/include/linux/irqnr.h
there's nothing there but a header reinclusion guard and a comment.
So just stick a comment in there as a placeholder.
Without this, if the kernel is fabricated from, say, a tarball and a patch, you
can get this error when building x86_64 or usermode Linux (and probably
others):

It seems I accidentally switched the guard on linux/elf-fdpic.h from #ifdef
__KERNEL__ to #ifndef __KERNEL__ when attempting to expand the guarded region
to cover the elf_fdpic_params struct when doing the UAPI split - with the
result that the struct became unavailable to kernel code.
Move incorrectly guarded bits back to the kernelspace header.
Whilst we're at it, the __KERNEL__ guards can be deleted as they're no longer
necessary.
