Enable UNALIGNED_ACCESS for the new LZO algorithm to use. LZO decrompression is used on QCACHE so we benefit a little from the new and improved LZO code.

binfmt_elf.c: use get_random_int() to fix entropy depleting

Entropy is quickly depleted under normal operations like ls(1), cat(1),
etc...  between 2.6.30 to current mainline, for instance:

$ cat /proc/sys/kernel/random/entropy_avail
3428
$ cat /proc/sys/kernel/random/entropy_avail
2911
$cat /proc/sys/kernel/random/entropy_avail
2620

We observed this problem has been occurring since 2.6.30 with
fs/binfmt_elf.c: create_elf_tables()->get_random_bytes(), introduced by
f06295b44c296c8f ("ELF: implement AT_RANDOM for glibc PRNG seeding").

/*
 * Generate 16 random bytes for userspace PRNG seeding.
 */
get_random_bytes(k_rand_bytes, sizeof(k_rand_bytes));

The patch introduces a wrapper around get_random_int() which has lower
overhead than calling get_random_bytes() directly.

With this patch applied:
$ cat /proc/sys/kernel/random/entropy_avail
2731
$ cat /proc/sys/kernel/random/entropy_avail
2802
$ cat /proc/sys/kernel/random/entropy_avail
2878

Staging: android: binder: Add binder buffers to kmemleak

Some binder_transaction structs are only referenced by a

msm: kgsl: Enable "big page" memory allocations

Allow users to specify "big page" mode when allocating GPU
memory. This will attempt to allocate contigious units of 64k
bytes per instead of the usual PAGE_SIZE units.  If the allocation
fails, then automatically fall back to allocate the rest of the
region with 4K pages. This means that potentially any allocation
could be comprised of a mixture of 64k chunks and 4k chunks.

msm: cpuidle: Don't disable irqs again

cpu_idle() disables irqs before calling down into the cpuidle
driver via cpuidle_idle_call(). Disabling irqs again in
msm_cpuidle_enter() is wasteful and unnecessary. It also inhibits
our ability to determine the largest irq latency when the cpu
idles for extended periods of time because the irqsoff trace is
reenabled when the irqs are disabled in msm_cpuidle_enter().

Note that we still reenable irqs before returning, as is required
by the ARM idle loop.

msm: dma: Moving queue_work() function within spinlock

Currently we are adding a dma command to the staged list with in a
spinlock and then adding to workqueue using queue_work after unlocking
the spinlock. With this there is chance of executing DMA commands in out
of order in below concurrency case.

Tread1                                Thread2
__msm_dmov_enqueue_cmd_ext
   spin_lock_irqsave(..)
   list_add_tail(..)
   spin_unlock_irqrestore(..)
       --PREEMPT--
                                      __msm_dmov_enqueue_cmd_ext
                                         spin_lock_irqsave(..)
                                         list_add_tail(..)
                                         spin_unlock_irqrestore(..)
                                         queue_work()
                                         ..
   queue_work()
So adding queue_work with in spin_lock will make sure that the
work added in the work_queue is processed in the same order as they
are added in staged_commands.

direct-io: don't read inode->i_blkbits multiple times

Since directio can work on a raw block device, and the block size of the
device can change under it, we need to do the same thing that
fs/buffer.c now does: read the block size a single time, using
ACCESS_ONCE().

Reading it multiple times can get different results, which will then
confuse the code because it actually encodes the i_blksize in
relationship to the underlying logical blocksize.

mmc: queue: amend buffer swap for non-blocking transfer

In case both 'req' and 'mq->mqrq_prev->req' are null, there is no request
to be processed. That means there is no need to switch buffer.
Switching buffer is required only after finishing 'issue_fn'.
