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

Pull MIPS fixes from Ralf Baechle:
 "Here's a final round of fixes for 4.12:

   - Fix misordered instructions in assembly code making kenel startup
     via UHB unreliable.

   - Fix special case of MADDF and MADDF emulation.

   - Fix alignment issue in address calculation in pm-cps on 64 bit.

   - Fix IRQ tracing & lockdep when rescheduling

   - Systems with MAARs require post-DMA cache flushes.

  The reordering fix and the MADDF/MSUBF fix have sat in linux-next for
  a number of days. The others haven't propagated from my pull tree to
  linux-next yet but all have survived manual testing and Imagination's
  automated test system and there are no pending bug reports"
