Merge git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile

Pull arch/tile updates from Chris Metcalf:
 "This adds support for an <arch/intreg.h> to help with removing
  __need_xxx #defines from glibc, and removes some dead code in
  arch/tile/mm/init.c"

* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
  mm, tile: drop arch_{add,remove}_memory
  tile: prefer <arch/intreg.h> to __need_int_reg_t
