Merge tag 'perf-core-for-mingo-20160506' 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: - Fix ordering of kernel/user entries in 'caller' mode, where the kernel and user parts were being correctly inverted but kept in place wrt each other, i.e. 'callee' (k1, k2, u3, u4) became 'caller' (k2, k1, u4, u3) when it should be 'caller' (u4, u3, k2, k1) (Chris Phlipot) - In 'perf trace' don't print the raw arg syscall args for a syscall that has no arguments, like gettid(). This was happening because just checking if the syscall args list is NULL may mean that there are no args (e.g.: gettid) or that there is no tracepoint info (e.g.: clone) (Arnaldo Carvalho de Melo) - Add extra output of counter values with 'perf stat -vv' (Andi Kleen) Infrastructure changes: - Expose callchain db export via the python API (Chris Phlipot) Code reorganization: - Move some more syscall arg beautifiers from the 'perf trace' main file to separate files in tools/perf/trace/beauty/, to reduce the main file line count (Arnaldo Carvalho de Melo) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
