# Merge: 70c9fb570b7c 6f55967ad9d9

# 
#     Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull perf fixes from Ingo Molnar:
#      "I'd like to apologize for this very late pull request: I was dithering
#       through the week whether to send the fixes, and then yesterday Jiri's
#       crash fix for a regression introduced in this cycle clearly marked
#       perf/urgent as 'must merge now'.
#     
#       Most of the commits are tooling fixes, plus there's three kernel fixes
#       via four commits:
#     
#         - race fix in the Intel PEBS code
#     
#         - fix an AUX bug and roll back a previous attempt
#     
#         - fix AMD family 17h generic HW cache-event perf counters
#     
#       The largest diffstat contribution comes from the AMD fix - a new event
#       table is introduced, which is a fairly low risk change but has a large
#       linecount"
#     
#     * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
