Merge tag 'arc-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc

Pull ARC updates from Vineet Gupta:
 "Sorry for the late pull request.  Current stuff was ready for a while
  but I was hoping to squeeze in support for almost ready ARC SDP
  platform (and avoid a 2nd pull request), however it seems there are
  still some loose ends which warrant more time.

   - Platform code reduction/moving-up (TB10X no longer needs any
     callbacks)
   - updated boot printing
   - kgdb update for arc gdb 7.5
   - bug fixes (some marked for stable)
   - more code refactoring/consolidation"

* tag 'arc-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc:
  ARC: boot: cpu feature print enhancements

  ARC: refactoring: reduce the scope of some local vars
  ARC: remove gcc mpy heuristics
  ARC: RIP @running_on_hw
