Merge tag 'perf-core-for-mingo-20160516' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: - Honour the kernel.perf_event_max_stack knob more precisely by not counting PERF_CONTEXT_{KERNEL,USER} when deciding when to stop adding entries to the perf_sample->ip_callchain[] array (Arnaldo Carvalho de Melo) - Fix identation of 'stalled-backend-cycles' in 'perf stat' (Namhyung Kim) - Update runtime using 'cpu-clock' event in 'perf stat' (Namhyung Kim) - Use 'cpu-clock' for cpu targets in 'perf stat' (Namhyung Kim) - Avoid fractional digits for integer scales in 'perf stat' (Andi Kleen) - Store vdso buildid unconditionally, as it appears in callchains and we're not checking those when creating the build-id table, so we end up not being able to resolve VDSO symbols when doing analysis on a different machine than the one where recording was done, possibly of a different arch even (arm -> x86_64) (He Kuang) Infrastructure changes: - Generalize max_stack sysctl handler, will be used for configuring multiple kernel knobs related to callchains (Arnaldo Carvalho de Melo) Cleanups: - Introduce DSO__NAME_KALLSYMS and DSO__NAME_KCORE, to stop using open coded strings (Masami Hiramatsu) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
