X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=69766c40c35de3a2c1142c43baa9951dfe11f002;p=deliverable%2Flinux.git Merge tag 'perf-urgent-for-mingo-20160809' of git://git./linux/kernel/git/acme/linux into perf/urgent Pull perf/urgent fixes from Arnaldo Carvalho de Melo: 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) - 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) Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Ingo Molnar --- 69766c40c35de3a2c1142c43baa9951dfe11f002
