Hi Ingo,
Please consider pulling,

The following changes since commit 9c17dbc6eb73bdd8a6aaea1baefd37ff78d86148:

perf tools: By default use the most precise "cycles" hw counter available (2015-09-30 18:34:39 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- By default use the most precise "cycles" hw counter available, i.e.
when the user doesn't specify any event, it will try using cycles:ppp,
cycles:pp, etc (Arnaldo Carvalho de Melo)
- Remove blank lines, headers when piping output in 'perf list', so that it can
be sanely used with 'wc -l', etc (Arnaldo Carvalho de Melo)
- Amend documentation about max_stack and synthesized callchains (Adrian Hunter)
- Fix 'perf probe -l' for probes added to kernel module functions (Masami Hiramatsu)
Build fixes:
- Fix shadowed declarations that break the build on older distros (Jiri Olsa)
- Fix build break on powerpc due to sample_reg_masks (Sukadev Bhattiprolu)

The perf_regs.c file does not get built on Powerpc as CONFIG_PERF_REGS
is false. So the weak definition for 'sample_regs_masks' doesn't get
picked up.
Adding perf_regs.o to util/Build unconditionally, exposes a redefinition
error for 'perf_reg_value()' function (due to the static inline version
in util/perf_regs.h). So use #ifdef HAVE_PERF_REGS_SUPPORT' around that
function.
