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

Pull MIPS fixes from Ralf Baechle:
 "Resurrect Alchemy platforms by invoking the WAIT instructions with
  interrupts enabled.  This still leaves the race condition between
  testing TIF_NEED_RESCHED and the WAIT instruction for Alchemy
  platforms which need a different fix than other MIPS platforms.  But
  at least it gets MIPS platforms flying again.

  There are also fixes for two build errors (CONFIG_FTRACE=y with
  CONFIG_DYNAMIC_FTRACE=n) and CONFIG_VIRTUALIZATION without CONFIG_KVM"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: ftrace: Add missing CONFIG_DYNAMIC_FTRACE
  MIPS: include: mmu_context.h: Replace VIRTUALIZATION with KVM
  MIPS: Alchemy: fix wait function
