Headset: Ability to hang-up a call from a wired audio headset

Address OPO_52.
The KEY_MEDIA and KEY_VOLUMEUP are mapped to multiple buttons.
That will confuse the input class driver when one button is
pressed while others are released. Fuse all buttons with same
function to one will fix the problem.

ASoC: wcd9xxx: Set chopper settings for UHQA mode

UHQA (Ultra High Quality Audio) requires chopper to set the
frequency to the actual frequency. Change enables chopper
to set the frequency to half for all audio streams
with different sampling rates and 24-bits per sample
other than UHQA mode.

ASoC: msm: qdsp6v2: Fix for cmd status overwrite

There is a race condition between offload callback thread
and HAL thread which can cause an eos ack notification to
be overwritten by a stop command request. Fix this by
using separate status vars for commands originating from
different thread contexts

Squash 'enhance power efficiency' patches

Series of patches from NVIDIA on some critical blocking
code paths to allow the CPU to relax instead of busy spinning
thus lowering the load_average and lowering power consumption.

cpufreq: cpu-boost: we can hit a small performance loss by not queuing input works less than 150ms apart when our default input work duration is only 40ms, so use that 40ms as a magic value instead of the 150ms minimum interval.

def: Add xbox controller support as module
namespace: Restrict slave mountspace so Dalvik apps can mount system-wide volumes (Variant 2)

--> version without remounting on /mnt/shell/emulated !!!

Android 4.2 implements multi-user storage using per-process mount
namespaces.  Everything under "/" (the entire filesystem hierarchy) is
marked as a recursive-slave mountspace for all zygote instances.  This is
done so that user-storage sandbox mounts under /storage/emulated are hidden
from other apps and users.

Unfortunately this means that any Dalvik app (actually, any program whose
clone/fork ancestry includes a Dalvik zygote, which is everything except
services spawned directly from init) cannot mount system-wide volumes.
Thus, apps like CifsManager are effectively broken in Android 4.2, since
its cifs mounts are only visible to the CifsManager app itself.  All other
apps see empty mountpoints instead of the mounted volume.  Furthermore,
Linux provides no provision for a process to "escape" a recursive-slave
mountspace in versions prior to Linux 3.8 (setns syscall).

Here, we restrict rootfs-slave calls to /storage (and, due to a possible
kernel bug, /mnt/shell/emulated) so that Dalvik apps can mount system-wide
volumes elsewhere (with appropriate permission, as in earlier versions of
Android), while retaining full multi-user storage compatibility.  It is
made available as a kernel-based workaround for instances where libdvm can
not be modified.

This change requires that a tmpfs volume is mounted as /storage in init.rc.
If this volume is unavailable, then we falls back to the previous behavior
of marking the entire filesystem hierarchy as slave.

*** Do not commit to CyanogenMod Project kernels, as a similar workaround
    for this problem is patched in Zygote/Dalvik/libdvm instead.  ***
