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.

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.
