mint: in-kernel mpdecision

Ported from Dennis Rassmann's work on the Bricked Mako kernel. Offers
extensive battery savings and more responsive touch input boost. No need
to wait for the kernel to tell userspace there is a touch event, which
then informs mpdecision which writes to sysfs and then back to the
kernel.

Also, seriously, why do we need a blob to decide when to online and
offline a core?

msm: kgsl: Use the kmalloc/vmalloc trick for the sharedmem page array

It was previously assumed that most GPU memory allocations would be
small enough to allow us to fit the array of page pointers into one
or two pages allocated via kmalloc.  Recent reports have proven
those assumptions to be wrong - allocations on the order of 32MB will
end up trying to get 8 pages from kmalloc and 8 contiguous pages
on a busy system are a rare beast indeed.

So use the usual kmalloc/vmalloc trick instead - use kmalloc for the
page array when we can and vmalloc if we can't.

msm: kgsl: Configure FT behaviour from sysfs instead of debugfs

FT behaviour is changed to be configured from sysfs
instead of debugfs. Sysfs control gives us the advantage
of configuring FT at bootup and also across bootups.
Persistant configuration across bootups helps
testing by configuring FT once and testing the FT
config across bootups.

ALSA: usb-audio: Fix the mixer control range limiting issue

- mixer_ctl_set() function is limiting the volume level
  to particular range. This results in incorrect initial
  volume setting for that device.
- In USB mixer while calculating the dBmin/dBmax values
  resolution factor is hardcoded to 256 which results in
  populating the wrong values for dBmin/dBmax.
- Fix is to use appropriate resolution factor while
  calculating the dBmin/dBmax values.

ARM: 7527/1: uaccess: explicitly check __user pointer when !CPU_USE_DOMAINS

The {get,put}_user macros don't perform range checking on the provided
__user address when !CPU_HAS_DOMAINS.

This patch reworks the out-of-line assembly accessors to check the user
address against a specified limit, returning -EFAULT if is is out of
range.

[will: changed get_user register allocation to match put_user]
[rmk: fixed building on older ARM architectures]

msm: scm: Add scm_call_noalloc and helper macros

Currently, scm_call internally calls kmalloc() to allocate a command
buffer structure. This prevents scm_call from working before kmalloc
structures are initialized or during atomic contexts. Allow clients
to pass in a pre-allocated buffer for scm_call to be used for internal
structures.
