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.

2014-01-15perf: tools: Fix cross buildingMark Rutland3-7/+9
Currently the feature-checks Makefile does not inherit $(CC), and calls cc rather than $(CROSS_COMPILE)gcc. Thus the feature checks invoke the native toolchain rather than the cross toolchain, and can identify features as available when they are not. This can break the build. Additionally the native pkg-config is always called as opposed to $(CROSS_COMPILE)pkg-config, so the wrong flags and paths may be passed to the cross compiler. This patch passes CROSS_COMPILE down to the feature-checks Makefile, and forces its use. Additionally pkg-config is replaced with $(CROSS_COMPILE)pkg-config via a new $(PKG_CONFIG) variable. This patch has been build tested on x86_64 and arm.

2014-01-13perf evlist: Introduce evlist__for_each() & friendsArnaldo Carvalho de Melo24-86/+151
For the common evsel list traversal, so that it becomes more compact. Use the opportunity to start ditching the 'perf_' from 'perf_evlist__', as discussed, as the whole conversion touches a lot of places, lets do it piecemeal when we have the chance due to other work, like in this case.

Getting rid of following build output: $ make O=/tmp/build/perf -C tools/perf/ install-bin ... make[3]: Nothing to be done for `plugins'. make[2]: Nothing to be done for `plugins'. ... which triggers when traceevent library needs to be rebuilt, but we have plugins built already.
