We need to initializa some fields (right now just a mutex) when we
allocate the per symbol annotation struct, so do it at the symbol
constructor instead of (ab)using the filter mechanism for that.

This way we remove one of the few cases we have for that symbol filter,
which will eventually led to removing it.

Merge tag 'perf-core-for-mingo-20160823' 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:

. 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 changes:

- 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)

with u8/u16/u32/u64 in decimal digits instead of hexadecimal.

casting are typed by x64 (or x32 for 32bit arch) by default.

It is a requirement from the perf TODO list[1]:

''The feature tests should be performed only when a file that needs those
  tests, or at least only when some .c or .h file will be rebuilt. An
  initial step would be for 'make install-doc' not to run the feature
  tests, there it is not needed at all.''

By adding 'install-doc' to the NON_CONFIG_TARGETS, it will skip running
the feature tests for such target. The Auto-detecting system features
list will not be displayed:

  $ make install-doc
    BUILD:   Doing 'make -j2' parallel build
