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

Pull MIPS fixes from Ralf Baechle:
 "Random fixes across arch/mips, essentially.

  One fix for an issue in get_user_pages_fast() which previously was
  discovered on x86, a miscalculation in the support for the MIPS MT
  hardware multithreading support, the RTC support for the Malta and a
  fix for a spurious interrupt issue that seems to bite only very
  special Malta configurations."

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: Malta: Don't crash on spurious interrupt.
  MIPS: Malta: Remove RTC Data Mode bootstrap breakage
  MIPS: mm: Add compound tail page _mapcount when mapped
  MIPS: CMP/SMTC: Fix tc_id calculation
