Add config dependency for Exynos4 and Exynos5 device tree enabled machine
files on config options ARCH_EXYNOS4 and ARCH_EXYNOS5 respectively.
Enabling machine support without proper ARCH support enabled is incorrect.

The atmel_mxt_ts driver has been extended to support more 'configuration
objects' in commit 81c88a711 ("Input: atmel_mxt_ts - update object list"),
what broke the configuration values for NURI board. These values are
optional anyway, so remove them to get the driver working correctly.

On some versions of NURI and UniversalC210 boards, camera clocks are
routed directly to xusbxti clock source. This patch sets the correct
value for this clock to let usb and camera sensors to work correctly and
avoid division by zero on driver's probe.

Now that we have OPP layer, and OMAP CPUfreq driver is using it, we no
longer need/use the clock framework code for filling up CPUfreq
tables. Remove it.
Removing this code also eliminates build errors when CPU_FREQ_TABLE
support is not enabled.
Thanks to Russell King for pointing out the parts I missed under
plat-omap in the original version and also pointing out the build
errors when CPUFREQ_TABLE support was not enabled.

These were incorrectly introduced and can cause problems for of_irq_init.
The correct way to define a root controller is no interrupt-parent set at
all or the interrupt-parent is set to the root controller itself when

Pull another round of sound fixes from Takashi Iwai:
"A few regression fixes for Realtek HD-audio codecs, mainly specific to
some laptop models."
* tag 'sound-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
ALSA: hda/realtek - Fix mem leak (and rid us of trailing whitespace).
ALSA: hda/realtek - Add quirk for Mac Pro 5,1 machines
ALSA: hda/realtek - Add a fixup entry for Acer Aspire 8940G

In sound/pci/hda/patch_realtek.c::alc_auto_fill_dac_nids(), in the
'for (;;)' loop, if the 'badness' value returned from
fill_and_eval_dacs() is negative, then we'll return from the function
without freeing the memory we allocated for 'best_cfg', thus leaking.
Fix the leak by kfree()'ing the memory when badness is negative.
While I was there I also noticed some trailing whitespace in the
function that I removed (along with all other trailing whitespace in
the file) - it didn't seem worth-while to do that as two patches, so I
hope it's OK that I just did it all as one patch.

A user reported that setting model=imac24 used to allow sound to work on their
Mac Pro 5,1 machine. Commit 5671087ffa "Move ALC885 macpro and imac24 models
to auto-parser" removed this model option. All Mac machines are now explicitly
handled with a quirk and the auto-parser. This adds a quirk for the device
found on the Mac Pro 5,1 machines.
This (partially) fixes https://bugzilla.redhat.com/show_bug.cgi?id=808559

Commit 18a4d0a22ed6 ("[SCSI] Handle disk devices which can not process
medium access commands") introduced a bug in which we would attempt to
dereference the scsi driver even when the device had no ULD attached.
Ensure that a driver is registered and make the driver accessor function
more resilient to errors during device discovery.

Running 'perf kvm --host --guest --guestmount /tmp/guestmount record -a -g -- sleep 2'
Was resulting in a segfault. For event type PERF_RECORD_MMAP,
event->ip.pid is being used in perf_session__find_machine_for_cpumode,
which is not correct.
The event->ip.pid field happens to be 0 in this case and results in
returning a NULL machine object. Finally, access to self->pid in
machine__mmap_name, results in a segfault later.
For PERF_RECORD_MMAP type, pass event->mmap.pid.

This routine was checking only if the provided address was after
sym->end, not if it was before sym->start.
Fix that by checking for both and return in both cases -ERANGE, so that
tools can communicate this to the user properly, or if they chose so, to
abort.
This problem was reported previously but the fixes involved either doing
what was being done for the > end case, i.e. silently drop the sample,
returning 0, or aborting at this function, which is in a lib (or better,
is slated to be at some point) and shouldn't abort.
The 'report' tool already checks this value and uses pr_debug to warn
the user.
This patch makes the 'top' tool check it too and warn once per map where
such range problem takes place.

If there's an event with no samples in data file, the perf report
command can segfault after entering the event details menu.
Following steps reproduce the issue:
# ./perf record -e syscalls:sys_enter_kexec_load,syscalls:sys_enter_mmap ls
# ./perf report
# enter '0 syscalls:sys_enter_kexec_load' menu
# pres ENTER twice
Above steps are valid assuming ls wont run kexec.. ;)
The check for sellection to be NULL is missing. The fix makes sure it's
being check. Above steps now endup with menu being displayed allowing
'Exit' as the only option.

When a process exec()'s, all the maps are retired, but we keep the hist
entries around which hold references to those outdated maps.
If the same library gets mapped in for which we have hist entries, a new
map will be created. But when we take a perf entry hit within that map,
we'll find the existing hist entry with the older map.
This causes symbol translations to be done incorrectly. For example,
the perf entry processing will lookup the correct uptodate map entry and
use that to calculate the symbol and DSO relative address. But later
when we update the histogram we'll translate the address using the
outdated map file instead leading to conditions such as out-of-range
offsets in symbol__inc_addr_samples().
Therefore, update the map of the hist_entry dynamically at lookup/
creation time.

We were only decaying the entries for the offsets that were associated
with an objdump line.
That way, when we accrued the whole instruction addr range, more than
100% was appearing in some cases in the live annotation TUI.
Fix it by not traversing the source code line at all, just iterate thru
the complete addr range decaying each one.

GCC's NULL is actually __null, which allows detecting some questionable
NULL usage and warn about it. Moreover each platform/compiler should
have its own stddef.h anyway (which is different from linux/stddef.h).
So there's no good reason to leak kernel's NULL to userspace and
override what the compiler provides.

Pull system.h fixups for less common arch's from Paul Gortmaker:
"Here is what is hopefully the last of the system.h related fixups.
The fixes for Alpha and ia64 are code relocations consistent with what
was done for the more mainstream architectures. Note that the
diffstat lines removed vs lines added are not the same since I've
fixed some of the whitespace issues in the relocated code blocks.
However they are functionally the same. Compile tested locally, plus
these two have been in linux-next for a while.
There is also a trivial one line system.h related fix for the Tilera
arch from Chris Metcalf to fix an implict include.."

"Fix ia64 build errors (fallout from system.h disintegration)"
introduced arch/ia64/include/asm/cmpxchg.h as a temporary
build fix and stated:
"... leave the migration of xchg() and cmpxchg() to this new
header file for a future patch."
Migrate the appropriate chunks from asm/intrinsics.h and fix
the whitespace issues in the migrated chunk.

"Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h"
introduced the concept of asm/cmpxchg.h but the alpha arch
never got one. Fork the cmpxchg content out of the asm/atomic.h
file to create one.
Some minor whitespace fixups were done on the block of code that
created the new file.

Pull the minimal btrfs branch from Chris Mason:
"We have a use-after-free in there, along with errors when mount -o
discard is enabled, and a BUG_ON(we should compile with UP more
often)."
* 'for-linus-min' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:
Btrfs: use commit root when loading free space cache
Btrfs: fix use-after-free in __btrfs_end_transaction
Btrfs: check return value of bio_alloc() properly
Btrfs: remove lock assert from get_restripe_target()
Btrfs: fix eof while discarding extents
Btrfs: fix uninit variable in repair_eb_io_failure

A user reported that booting his box up with btrfs root on 3.4 was way
slower than on 3.3 because I removed the ideal caching code. It turns out
that we don't load the free space cache if we're in a commit for deadlock
reasons, but since we're reading the cache and it hasn't changed yet we are
safe reading the inode and free space item from the commit root, so do that
and remove all of the deadlock checks so we don't unnecessarily skip loading
the free space cache. The user reported this fixed the slowness. Thanks,

49b25e0540904be0bf558b84475c69d72e4de66e introduced a use-after-free bug
that caused spurious -EIO's to be returned.
Do the check before we free the transaction.

bio_alloc() has the possibility of returning NULL.
So, it is necessary to check the return value.

This fixes a regression introduced by fc67c450. spin_is_locked() always
returns 0 on UP kernels, which caused assert in get_restripe_target() to
be fired on every call from btrfs_reduce_alloc_profile() on UP systems.
Remove it completely for now, it's not clear if it's going to be needed
in future.

We miscalculate the length of extents we're discarding, and it leads to
an eof of device.

We'd have to be passing bogus extent buffers for this uninit variable to
actually be used, but set it to zero just in case.

This reverts commit 5500cdbe14d7435e04f66ff3cfb8ecd8b8e44ebf.
We've had a number of complaints of early enospc that bisect down
to this patch. We'll hae to fix the reservations differently.
