1) Rework the sparc32 page tables so that READ_ONCE(*pmd), as done by
generic code, operates on a word sized element. From Will Deacon.
2) Some scnprintf() conversions, from Chen Zhou.
3) A pin_user_pages() conversion from John Hubbard.
4) Several 32-bit ptrace register handling fixes and such from Al Viro.
Please pull, thanks a lot!
