Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

Pull MIPS fixes from Ralf Baechle:
 "A collection of fixes pretty much across the MIPS code.  Even the
  change to include/linux/signal.h by David Howells' 2a1486981c ("Fix
  breakage in MIPS siginfo handling") should be considered MIPS-specific
  as it touches an ifdefed segment that is only relevant to MIPS and
  which unfortunately can't be made to go away entirely."
