Merge tag 'perf-core-for-mingo-20160506' of... 

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)
