Subject: [GIT] Sparc


Please pull to get these two bug fixes:

1) Fix boots with gcc-4.9 compiled sparc64 kernels.

2) Add missing __get_user_pages_fast() on sparc64 to fix hangs
   on futexes used in transparent hugepage areas.

   It's really idiotic to have a weak symbolled fallback that just
   returns zero, and causes this kind of bug.  There should be no
   backup implementation and the link should fail if the architecture
   fails to provide __get_user_pages_fast() and supports transparent
   hugepages.

Thanks.
