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

Pull MIPS updates from Ralf Baechle:
 "Eight fixes across arch/mips.  Nothing stands particuarly out nor is
  complicated but fixes keep coming in at a higher than comfortable
  rate"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: KVM: Do not sign extend on unsigned MMIO load
  MIPS: BPF: Fix stack pointer allocation
  MIPS: Loongson-3: Fix a cpu-hotplug issue in loongson3_ipi_interrupt()
  MIPS: Fix enabling of DEBUG_STACKOVERFLOW
  MIPS: c-r4k: Fix typo in probe_scache()
  MIPS: Avoid an FPE exception in FCSR mask probing
  MIPS: ath79: Add a missing new line in log message
  MIPS: ralink: Fix clearing the illegal access interrupt
