Merge tag 'arc-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC architecture updates from Vineet Gupta: "ARC updates for 4.3: - perf support for ARCv2 based cores (sampling interrupt, SMP) - leftovers for ARCv2 support - futex fixes" * tag 'arc-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: ARCv2: entry: Fix reserved handler ARCv2: perf: Finally introduce HS perf unit ARCv2: perf: SMP support ARCv2: perf: implement exclusion of event counting in user or kernel mode ARCv2: perf: Support sampling events using overflow interrupts ARCv2: perf: implement "event_set_period" ARC: perf: cap the number of counters to hardware max of 32 ARC: Eliminate some ARCv2 specific code for ARCompact build ARC: add/fix some comments in code - no functional change ARC: change some branchs to jumps to resolve linkage errors ARC: ensure futex ops are atomic in !LLSC config ARC: Enable HAVE_FUTEX_CMPXCHG ARC: make futex_atomic_cmpxchg_inatomic() return bimodal ARC: futex cosmetics ARC: add barriers to futex code ARCv2: IOC: Allow boot time disable ARCv2: SLC: Allow boot time disable ARCv2: Support IO Coherency and permutations involving L1 and L2 caches ARC: Enable optimistic spinning for LLSC config MAINTAINERS: add git tree for the arc architecture
