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 Signed-off-by: Rebecca Schultz <rschultz@google.com> 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. Signed-off-by: Rebecca Schultz Zavin <rebecca@android.com> pmem: Remove unused depricated fd api to pmem. Signed-off-by: Rebecca Schultz Zavin <rebecca@android.com> 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.
