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"
