Among the few patches that we have so far, there's a few noticeable changes:
- Introduction of the Allwinner A23 SoC
- Support for the GMAC on the A31. This is only available so far on the
boards which bootloader enable the PHY regulator.
- Addition of the infrared receiver

commit 99994cd btrfs: dev delete should remove sysfs entry
added a btrfs_kobj_rm_device, which dereferences device->bdev...
right after we check whether device->bdev might be NULL.
I don't honestly know if it's possible to have a NULL device->bdev
here, but assuming that it is (given the test), we need to move
the kobject removal to be under that test.

xfstests generic/127 detected this problem.
With commit 7fc34a62ca, now fsync will only flush
data within the passed range. This is the cause of the above problem,
-- btrfs's fsync has a stage called 'sync log' which will wait for all the
ordered extents it've recorded to finish.
In xfstests/generic/127, with mixed operations such as truncate, fallocate,
punch hole, and mapwrite, we get some pre-allocated extents, and mapwrite will
mmap, and then msync. And I find that msync will wait for quite a long time
(about 20s in my case), thanks to ftrace, it turns out that the previous
fallocate calls 'btrfs_wait_ordered_range()' to flush dirty pages, but as the
range of dirty pages may be larger than 'btrfs_wait_ordered_range()' wants,
there can be some ordered extents created but not getting corresponding pages
flushed, then they're left in memory until we fsync which runs into the
stage 'sync log', and fsync will just wait for the system writeback thread
to flush those pages and get ordered extents finished, so the latency is
inevitable.
This adds a flush similar to btrfs_start_ordered_extent() in
btrfs_wait_logged_extents() to fix that.

random: check for increase of entropy_count because of signed conversion
Pull crypto fixes from Herbert Xu:
"This push fixes a boot hang in virt guests when the virtio RNG is
enabled"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
hwrng: virtio - ensure reads happen after successful probe
hwrng: fetch randomness only after device init
The expression entropy_count -= ibytes << (ENTROPY_SHIFT + 3) could
actually increase entropy_count if during assignment of the unsigned
expression on the RHS (mind the -=) we reduce the value modulo
2^width(int) and assign it to entropy_count. Trinity found this.
[ Commit modified by tytso to add an additional safety check for a
negative entropy_count -- which should never happen, and to also add
an additional paranoia check to prevent overly large count values to
be passed into urandom_read(). ]

When CPU topology is specified in device tree, cpu_logical_map() does
not return core ID anymore, but rather full MPIDR value. This breaks
existing calculation of PMU register offsets on Exynos SoCs.
This patch fixes the problem by adjusting the code to use only core ID
bits of the value returned by cpu_logical_map() to allow CPU topology to
be specified in device tree on Exynos SoCs.

Merge tag 'xfs-for-linus-3.16-rc5' of git://oss.sgi.com/xfs/xfs
Pull xfs fixes from Dave Chinner:
"Fixes for low memory perforamnce regressions and a quota inode
handling regression.
These are regression fixes for issues recently introduced - the change
in the stack switch location is fairly important, so I've held off
sending this update until I was sure that it still addresses the stack
usage problem the original solved. So while the commits in the xfs
tree are recent, it has been under tested for several weeks now"
* tag 'xfs-for-linus-3.16-rc5' of git://oss.sgi.com/xfs/xfs:
xfs: null unused quota inodes when quota is on
xfs: refine the allocation stack switch
Revert "xfs: block allocation work needs to be kswapd aware"
The pwm driver requires a clocks property referencing the pwm peripheral

Certain GIC implementation, namely those found on earlier, single
cluster, Exynos SoCs, have registers mapped without per-CPU banking,
which means that the driver needs to use different offset for each CPU.
Currently the driver calculates the offset by multiplying value returned
by cpu_logical_map() by CPU offset parsed from DT. This is correct when
CPU topology is not specified in DT and aforementioned function returns
core ID alone. However when DT contains CPU topology, the function
changes to return cluster ID as well, which is non-zero on mentioned
SoCs and so breaks the calculation in GIC driver.
This patch fixes this by masking out cluster ID in CPU offset
calculation so that only core ID is considered. Multi-cluster Exynos
SoCs already have banked GIC implementations, so this simple fix should
be enough.
