Pull x86 cleanups from Thomas Gleixner:
 "A set of x86 cleanups:

   - Rework the handling of x86_regset for 32 and 64 bit.

     The original implementation tried to minimize the allocation size
     with quite some hard to understand and fragile tricks. Make it
     robust and straight forward by separating the register enumerations
     for 32 and 64 bit completely.

   - Add a few missing static annotations

   - Remove the stale unused setup_once() assembly function

   - Address a few minor static analysis and kernel-doc warnings"
