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

Pull MIPS fixes from Ralf Baechle:
 "This is dominated by a large number of changes necessary for the MIPS
  BPF code.  code.  Aside of that there are

   - a fix for the MSC system controller support code.
   - a Turbochannel fix.
   - a recordmcount fix that's MIPS-specific.
   - barrier fixes to smp-cps / pm-cps after unrelated changes elsewhere
     in the kernel.
   - revert support for MSA registers in the signal frames.  The
     reverted patch did modify the signal stack frame which of course is
     inacceptable.
   - fix math-emu build breakage with older compilers.
   - some related cleanup.
   - fix Lasat build error if CONFIG_CRC32 isn't set to y by the user"
