msm: msm_fb: Do not use ION_IOMMU_UNMAP_DELAYED flag.

Since iommu buffers will be unmapped after two newer commits
had passed, there is no need to request iommu driver to further
delay unmapping an iommu buffer.

msm: implement ARCH_RANDOM

Currently, the software random number generator is not intialized
until relatively late in the boot process. Software that relies on
random numbers early will not be reliable. Entropy sources are
available early but not early enough for some use cases which means
that moving the software random number generation earlier is not an
option. As an alternate solution, implement the functions associated
with CONFIG_ARCH_RANDOM. These functions currently make a call into
trustzone to get reliable random numbers. The functions are disabled
once the regular random number generator is sufficiently reliable.

seq_file: Allocate memory using vmalloc when kmalloc failed

When dumpstate access /proc/xxx/binder, this binder include lots of info,
it will use seq_read in kernel, in this function, it will trigger
high order memory alloc, when read binder info or other large file,
this will cause memory presure when system don't have contious high order
memory, it will lead to high kswap workload to reclaim the page. so change
kmalloc to vmalloc, it can avoid contiously high order memory allocating.

mm: Don't use CMA page for file cache

Despite the best efforts of redirection, the file system may still
allocate CMA pages with references held for long periods of time.
If a CMA page ends up being allocated, free it and get a non-CMA page.

ASoC:msm: Increase Proxy buffering

-Proxy buffering can overflow if BT

-Fix this by increasing the proxy

ARM: 7743/1: compressed/head.S: work around new binutils warning

commit da94a829305f1c217cfdf6771cb1faca0917e3b9 upstream.

In August 2012, Matthew Gretton-Dann checked a change into binutils
labelled "Error on obsolete & warn on deprecated registers", apparently as
part of ARMv8 support. Apparently, this was supposed to emit the message
"Warning: This coprocessor register access is deprecated in ARMv8" when
using certain mcr/mrc instructions and building for ARMv8. Unfortunately,
the message that is actually emitted appears to be '(null)', which is
less helpful in comparison.

Even more unfortunately, this is biting us on every single kernel
build with a new gas, because arch/arm/boot/compressed/head.S and some
other files in that directory are built with -march=all since kernel
commit 80cec14a8 "[ARM] Add -march=all to assembly file build in
arch/arm/boot/compressed" back in v2.6.28.

This patch reverts Russell's nice solution and instead marks the head.S
file to be built for armv7-a, which fortunately lets us build all
instructions in that file without warnings even on the broken binutils.

Without this patch, building anything results in:

arch/arm/boot/compressed/head.S: Assembler messages:
arch/arm/boot/compressed/head.S:565: Warning: (null)
