Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull two sparc fixes from David Miller:
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.
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
sparc64: Implement __get_user_pages_fast().
sparc64: Fix register corruption in top-most kernel stack frame during boot.
