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"
