Merge tag 'perf-urgent-2020-12-06' of git://git./linux/kernel/git/tip/tip

Pull perf fixes from Thomas Gleixner:
 "Two fixes for performance monitoring on X86:

   - Add recursion protection to another callchain invoked from
     x86_pmu_stop() which can recurse back into x86_pmu_stop(). The
     first attempt to fix this missed this extra code path.

   - Use the already filtered status variable to check for PEBS counter
     overflow bits and not the unfiltered full status read from
     IA32_PERF_GLOBAL_STATUS which can have unrelated bits check which
     would be evaluated incorrectly"
