Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Thomas Gleixner:
"Two small fixes for perf:
- the move to support cross arch annotation introduced per arch
initialization requirements, fullfill them for s/390 (Christian
Borntraeger)
- add the missing initialization to the LBR entries to avoid exposing
random or stale data"
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
perf/x86: Avoid exposing wrong/stale data in intel_pmu_lbr_read_32()
perf annotate s390: Fix perf annotate error -95 (4.10 regression)
