  perf probe ppc64le: Fix probe location when using DWARF (2016-08-09 12:14:29 -0300)

----------------------------------------------------------------
perf/urgent fixes:

User visible fixes:

- Fix the lookup for a kernel module in 'perf probe', fixing for instance, the
  erroneous return of "[raid10]" when looking for "[raid1]"  (Konstantin Khlebnikov)

- Disable counters in a group before reading them in 'perf stat', to avoid skew (Mark Rutland)

- Fix adding probes to function aliases in systems using kaslr (Masami Hiramatsu)

- Trip libtraceevent trace_seq buffers, removing unnecessary memory usage that could
  bring a system using tracepoint events with 'perf top' to a crawl, as the trace_seq
  buffers start at a whooping 4 KB, which is very rarely used in perf's usecases,
  so realloc it to the really used space as a last measure after using libtraceevent
  functions to format the fields of tracepoint events (Arnaldo Carvalho de Melo)

- Fix 'perf probe' location when using DWARF on ppc64le (Ravi Bangoria)

Improvement:

- Allow specifying signedness casts to a 'perf probe' variable, to shorten
  the number of steps to see signed values that otherwise would always appear
  as hex values (Naohiro Aota)

Documentation fixes:

- Add 'bpf-output' field to 'perf script' usage message (Brendan Gregg)

Infrastructure fixes:

- Sync kernel header files: cpufeatures.h, {disabled,required}-features.h,
  bpf.h and vmx.h, so that we get a clean build, without warnings about files
  being different from the kernel counterparts.

  A verification of the need or desirability of changes in tools/ based on what
  was done in the kernel changesets was made and documented in the respective
  file sync changesets (Arnaldo Carvalho de Melo)
