Proposed changes for the RTAS subsystem and client code.
Fixes that are subject to backporting are at the front of the queue,
followed by documentation and cleanups, with enhancements at the end.
Noteworthy changes:
* Change sys_rtas() to consume -2/990x statuses instead of returning
them to user space.
* Lockdep annotations for invariants in rtas.c.
