    Subject[PATCH 0/3 v2] nmi perf fixes
    Fixes to allow unknown nmis to pass through the perf nmi handler instead
    of being swallowed. Contains patches that are already in Ingo's tree. Added
    here for completeness. Based on ingo/tip

    Tested on intel/amd

    v2: patch cleanups and consolidation, no code changes

    Peter Zijlstra (1):
