Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next

Pull sparc updates from David Miller:

 - Rework the sparc32 page tables so that READ_ONCE(*pmd), as done by
   generic code, operates on a word sized element. From Will Deacon.

 - Some scnprintf() conversions, from Chen Zhou.

 - A pin_user_pages() conversion from John Hubbard.

 - Several 32-bit ptrace register handling fixes and such from Al Viro.
