Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core updates from Arnaldo Carvalho de Melo: Changes in user visible interfaces: * Rename 'record's --no-delay option to --no-buffering, better reflecting its purpose and freeing up '--delay' to take the place of '--initial-delay', so that 'record' and 'stat' are consistent. Refactorings: * Get rid of die() and friends (good riddance!) in libtraceevent (Namhyung Kim) Infrastructure enhancements: * Fix cross build problems related to pkgconfig and CROSS_COMPILE not being propagated to the feature tests, leading to features being tested in the host and then being enabled on the target. (Mark Rutland) * Fix pointer-integer size mismatch in some libtraceevent plugins (Mark Rutland) * Fix build error due to zfree() cast (Namhyung Kim) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
