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

From: Don Zickus
Date: Tue May 27 2014 - 12:30:05 EST


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
