  Merge: 84c37c1 0acf611

      Merge tag 'extable-fix' of 
git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux
      
      Pull extable.h fix from Paul Gortmaker:
       "Fixup for arch/score after extable.h introduction.
      
        It seems that Guenter is the only one on the planet doing builds for
        arch/score -- we don't have compile coverage for it in linux-next or
        in the kbuild-bot either. Guenter couldn't even recall where he got
        his toolchain, but was kind enough to share it with me so I could
        validate this change and also add arch/score to my build coverage.
      
        I sat on this a bit in case there was any other fallout in other arch
        dirs, but since this still seems to be the only one, I might as well
        send it on its way"

        score: Fix implicit includes now failing build after extable change
  
  commit 0acf611997d9d05dbfb559c3c6e379c861eb5957
  Author: Guenter Roeck <linux@xxxxxxxxxxxx>
  Date:   Wed Feb 22 11:07:57 2017 -0800
  
      score: Fix implicit includes now failing build after extable change
      
      After changing from module.h to extable.h, score builds fail with:
      
        arch/score/kernel/traps.c: In function 'do_ri':
        arch/score/kernel/traps.c:248:4: error: implicit declaration of 
function 'user_disable_single_step'
        arch/score/mm/extable.c: In function 'fixup_exception':
        arch/score/mm/extable.c:32:38: error: dereferencing pointer to 
incomplete type
        arch/score/mm/extable.c:34:24: error: dereferencing pointer to 
incomplete type
      
      because extable.h doesn't drag in the same amount of headers as the
      module.h did.  Add in the headers which were implicitly expected.
      
      Fixes: 90858794c960 ("module.h: remove extable.h include now users have 
migrated")
