Merge branch 'perf-urgent-for-linus' of git://git./linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
 "This update has mostly fixes, but also other bits:

   - perf tooling fixes

   - PMU driver fixes

   - Intel Broadwell PMU driver HW-enablement for LBR callstacks

   - a late coming 'perf kmem' tool update that enables it to also
     analyze page allocation data.  Note, this comes with MM tracepoint
     changes that we believe to not break anything: because it changes
     the formerly opaque 'struct page *' field that uniquely identifies
     pages to 'pfn' which identifies pages uniquely too, but isn't as
     opaque and can be used for other purposes as well"
