SELinux: include definition of new capabilities

The kernel has added CAP_WAKE_ALARM and CAP_EPOLLWAKEUP.  We need to
define these in SELinux so they can be mediated by policy.

msm: vidc: Check validity of userspace address

Before writing to a userspace address, verification
of the validity of user space address is required.

ALSA: pcm: check for integer overflow during multiplication

Channel info data structure is parsed from userspace and if
user does not set the no. of channels correctly, it could lead
to security vulnerability if we don't check for overflow when the
no. of channels is multiplied with pcm bit width. Add a condition
to check for overflow during multiplication.

qt602240_ts: updated touchscreen driver in according of Multi-touch protocol
our device is a type A device, in according with multi-touch protocol
https://www.kernel.org/doc/Documentation/input/multi-touch-protocol.txt
i made these changes on event semantics:
-changed ABS_MT_TOUCH_MAJOR to ABS_MT_PRESSURE
-changed ABS_MT_WIDTH_MAJOR to ABS_MT_TOUCH_MAJOR
-some cleanups with BTN_TOUCH report key

Note: in order to work is necessary to remove the flag BOARD_USE_LEGACY_TOUCHSCREEN in the BoardConfig of the device
defconfig: add CONFIG_CGROUP_MEM_RES_CTLR_SWAP_ENABLED. Picked from alviteri
defconfig: enable exfat support for ancora_tmo
aries: add extra free kbytes tunable

Add a userspace visible knob to tell the VM to keep an extra amount
of memory free, by increasing the gap between each zone's min and
low watermarks.

This is useful for realtime applications that call system
calls and have a bound on the number of allocations that happen
in any short time period.  In this application, extra_free_kbytes
would be left at an amount equal to or larger than than the
maximum number of allocations that happen in any burst.

It may also be useful to reduce the memory use of virtual
machines (temporarily?), in a way that does not cause memory
fragmentation like ballooning does.

[ccross]
Revived for use on old kernels where no other solution exists.
The tunable will be removed on kernels that do better at avoiding
direct reclaim.
