Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar: "This tree includes an x86 PMU scheduling fix, but most changes are late breaking tooling fixes and updates: User visible fixes: - Create config.detected into OUTPUT directory, fixing parallel builds sharing the same source directory (Aaro Kiskinen) - Allow to specify custom linker command, fixing some MIPS64 builds. (Aaro Kiskinen) - Fix to show proper convergence stats in 'perf bench numa' (Srikar Dronamraju) User visible changes: - Validate syscall list passed via -e argument to 'perf trace'. (Arnaldo Carvalho de Melo) - Introduce 'perf stat --per-thread' (Jiri Olsa) - Check access permission for --kallsyms and --vmlinux (Li Zhang) - Move toggling event logic from 'perf top' and into hists browser, allowing freeze/unfreeze with event lists with more than one entry (Namhyung Kim) - Add missing newlines when dumping PERF_RECORD_FINISHED_ROUND and showing the Aggregated stats in 'perf report -D' (Adrian Hunter) Infrastructure fixes: - Add missing break for PERF_RECORD_ITRACE_START, which caused those events samples to be parsed as well as PERF_RECORD_LOST_SAMPLES. ITRACE_START only appears when Intel PT or BTS are present, so.. (Jiri Olsa) - Call the perf_session destructor when bailing out in the inject, kmem, report, kvm and mem tools (Taeung Song) Infrastructure changes: - Move stuff out of 'perf stat' and into the lib for further use (Jiri Olsa) - Reference count the cpu_map and thread_map classes (Jiri Olsa) - Set evsel->{cpus,threads} from the evlist, if not set, allowing the generalization of some 'perf stat' functions that previously were accessing private static evlist variable (Jiri Olsa) - Delete an unnecessary check before the calling free_event_desc() (Markus Elfring) - Allow auxtrace data alignment (Adrian Hunter) - Allow events with dot (Andi Kleen) - Fix failure to 'perf probe' events on arm (He Kuang) - Add testing for Makefile.perf (Jiri Olsa) - Add test for make install with prefix (Jiri Olsa) - Fix single target build dependency check (Jiri Olsa) - Access thread_map entries via accessors, prep patch to hold more info per entry, for ongoing 'perf stat --per-thread' work (Jiri Olsa) - Use __weak definition from compiler.h (Sukadev Bhattiprolu) - Split perf_pmu__new_alias() (Sukadev Bhattiprolu)" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (54 commits) perf tools: Allow to specify custom linker command perf tools: Create config.detected into OUTPUT directory perf mem: Fill in the missing session freeing after an error occurs perf kvm: Fill in the missing session freeing after an error occurs perf report: Fill in the missing session freeing after an error occurs perf kmem: Fill in the missing session freeing after an error occurs perf inject: Fill in the missing session freeing after an error occurs perf tools: Add missing break for PERF_RECORD_ITRACE_START perf/x86: Fix 'active_events' imbalance perf symbols: Check access permission when reading symbol files perf stat: Introduce --per-thread option perf stat: Introduce print_counters function perf stat: Using init_stats instead of memset perf stat: Rename print_interval to process_interval perf stat: Remove perf_evsel__read_cb function perf stat: Move perf_stat initialization counter process code perf stat: Move zero_per_pkg into counter process code perf stat: Separate counters reading and processing perf stat: Introduce read_counters function perf stat: Introduce perf_evsel__read function ...
