Took the all the patches for pmem from the android branch:

pmem: Add pmem driver

Signed-off-by: Rebecca Schultz <rschultz@google.com>

pmem: Use the thread group leader insted of the current thread.

Instead of keeping track of the current thread, use the thread group leader

pmem: Add some apis to reference and flush pmem files by file struct

The api to refer to pmem files by fd should be depricated, it can
cause problems if a processes fd table changes while the kernel is processing
data in a pmem file.  This change adds the safer api.

pmem: Remove unused depricated fd api to pmem.

pmem: Remove error message when calling get_pmem_addr

This call is used from the mdp driver to determine if the memory
is in pmem or in the fb.  We will encounter this case during normal operation
so this error message should be removed.
