Hi Ingo,

Please consider pulling, I first merged tip/perf/urgent into a
tip/perf/core and rebased the patches I had in acme/perf/core.

perf record: Fix spelling mistake "Finshed" -> "Finished" (2016-08-23 17:06:40 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

. Allow configuring the default 'perf report -s' sort order in ~/.perfconfig,
for instance, "sym,dso" may be more fitting for kernel developers. (Arnaldo Carvalho de Melo)

- Support x8/x16/x32/x64 hexadecimal "types" in ftrace and 'perf probe' (Masami Hiramatsu)

Infrastructure:

- Skip running the feature tests for 'make install-doc' (Rui Teng)

- Introduce tools/include/linux/time64.h with *SEC_PER_*SEC macros
to use in all of tools/ (Arnaldo Carvalho de Melo)

- Break down symbol__disassemble() into multiple functions, to ease
future work on better reporting the errors that may take place in
the various steps it performs (possibly decompressing kernel module
files, getting build-id keyed files, calling objdump, parsing its
output, etc) (Arnaldo Carvalho de Melo)

- Typo fixes in various places (Colin Ian King)

- Remove superfluous NULL check in the TUI code (Colin Ian King)

- Allow displaying multiple header lines in the TUI browser, prep
work for the 'perf c2c' browser (Jiri Olsa)

- Copy coresight-pmu.h header file needed by perf tools (Mathieu Poirier)

- Use __weak definition from linux/compiler.h (Rui Teng)

News:

The fedora:24-x-ARC-uClibc adds the ARC arch and the uClibc libc to the mix of
targets tested, still with a minimal build that doesn't include even libelf,
that will be added soon, using a more full featured pre-built toolchain provided
by the Synopsys folks.
