Pull tile fixes from Chris Metcalf:
 "This fixes one issue with compiler flags that can cause modules not to
  load, and cleans up some warnings with ELF_R_xxx defines."

* 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
  arch/tile: avoid build warnings from duplicate ELF_R_xxx #defines
  arch/tile: avoid generating .eh_frame information in modules
