Pull ARC changes from Vineet Gupta: "Mostly cleanup/refactoring in core intc, cache flush, IPI send..." * tag 'arc-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: mm, arc: remove obsolete pagefault oom killer comment ARC: help gcc elide icache helper for !SMP ARC: move common ops for line/full cache into helpers ARC: cache boot reporting updates ARC: [intc] mask/unmask can be hidden again ARC: [plat-arcfpga] No need for init_irq hack ARC: [intc] don't mask all IRQ by default ARC: prune extra header includes from smp.c ARC: update some comments ARC: [SMP] unify cpu private IRQ requests (TIMER/IPI)
