Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: New features: - Make -a/--all-cpus be the default target in 'perf record' and 'perf stat', just like it is with 'perf trace' (Jiri Olsa) - Introduce -q/--quiet to the 'annotate', 'diff' and 'report', fix up its behaviour in 'record'. This makes the output more compact by elliminating headers, leaving just the histogram lines (Namhyung Kim) Fixes: - Handle offline/absent CPUs (Jan Stancek) Infrastructure changes: - Filter out -specs=/a/b/c from CC options when building the python support, allowing that feature to be built with clang (Arnaldo Carvalho de Melo) - Fix DEBUG=1 build with clang (Arnaldo Carvalho de Melo) Trivial changes: - Fix spelling of 'preempt' in a libtraceevent function name (Steven Rostedt) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
