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
