[PATCH 0/7 V4] perf: Enable mmap2 and add dcacheline sorting

[Don Zickus <dzickus@redhat.com>]

These patches enable mmap2 support in the kernel and perf to
allow support for data cacheline sorting.

Note: I haven't been able to reproduce Jiri's perf hang yet, so I don't
have a patch for that particular problem yet.

V4: reworked setting up cacheline size (Jiri Olsa)

V3: added patch to get cacheline size at runtime
    updated some changelogs
    fix a test failure (after install libunwind-devel)
    fix header column length

V2: change cacheline to dcacheline (Namhyung Kim)
    change dcacheline alogorithm a bit
    re-order mmap2 patches (Namhyung Kim)
    provide documentation (Andi Kleen)

Don Zickus (7):
  events, perf: Pass protection and flags bits through mmap2 interface
  Revert "perf: Disable PERF_RECORD_MMAP2 support"
  perf: Update mmap2 interface with protection and flag bits
  perf report: Add mem-mode documentation to report command
  perf: Add cpumode to struct hist_entry
  perf: Add support to dynamically get cacheline size
  perf: Add dcacheline sort
