Qais Yousef 99aa573db4 ANDROID: fs/proc: Perform priority inheritance around access_remote_vm() 
It holds mmap_sem lock which is a hot path. Some debug daemons can end
up holding this lock to get the cmdline of a process, which can result
in slowing down this process.

Add hooks around the calls to allow vendors to implement a simple prio
inheritance scheme to deal with this.
