Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle: "The two indirect syscall fixes have sat in linux-next for a few days. I did check back with a hardware designer to ensure a SYNC is really what's required for the GIC fix and so the GIC fix didn't make it into to linux-next in time for this final pull request. It builds in local build tests and passes Imagination's test system" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: irqchip: mips-gic: SYNC after enabling GIC region MIPS: Remove pt_regs adjustments in indirect syscall handler MIPS: seccomp: Fix indirect syscall args
