Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

perf/core improvements and fixes:

 * Improve 'perf bench' docs, by Namhyung Kim

 * Fix build when O= is not used, from David Ahern

 * Fix cross compilation build, from Namhyung Kim

 * Fix pipe mode when callchains are used, from David Ahern

 * Follow .gnu_debuglink section to find separate symbols, from Pierre-Loup A. Griffais

 * Fix 'perf test' raw events entries, from Jiri Olsa

 * Use the events description in the perf.data file, not the sysfs ones.
