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)
