Intel Dominates The Perf Changes For Linux 4.2

For those using perf for Linux profiling with performance counters, the Linux 4.2 kernel will bring many improvements to benefit Intel customers.

The perf changes for Linux 4.2 bring improvements for the Intel PT hardware CPU tracer, better Intel CQM (Cache Quality Monitoring), PEBSv3 support, and PEBS interrupt batching support. There are also PMU scheduler fixes/improvements, new perf sub-commands, and various other changes.

More details on the perf changes for Linux 4.2 via the pull request sent in earlier this week by Ingo Molnar.
