Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf changes from Ingo Molnar: "Kernel side changes: - Consolidate the PMU interrupt-disabled code amongst architectures (Vince Weaver) - misc fixes Tooling changes (new features, user visible changes): - Add support for pagefault tracing in 'trace', please see multiple examples in the changeset messages (Stanislav Fomichev). - Add pagefault statistics in 'trace' (Stanislav Fomichev) - Add header for columns in 'top' and 'report' TUI browsers (Jiri Olsa) - Add pagefault statistics in 'trace' (Stanislav Fomichev) - Add IO mode into timechart command (Stanislav Fomichev) - Fallback to syscalls:* when raw_syscalls:* is not available in the perl and python perf scripts. (Daniel Bristot de Oliveira) - Add --repeat global option to 'perf bench' to be used in benchmarks such as the existing 'futex' one, that was modified to use it instead of a local option. (Davidlohr Bueso) - Fix fd -> pathname resolution in 'trace', be it using /proc or a vfs_getname probe point. (Arnaldo Carvalho de Melo) - Add suggestion of how to set perf_event_paranoid sysctl, to help non-root users trying tools like 'trace' to get a working environment. (Arnaldo Carvalho de Melo) - Updates from trace-cmd for traceevent plugin_kvm plus args cleanup (Steven Rostedt, Jan Kiszka) - Support S/390 in 'perf kvm stat' (Alexander Yarygin) Tooling infrastructure changes: - Allow reserving a row for header purposes in the hists browser (Arnaldo Carvalho de Melo) - Various fixes and prep work related to supporting Intel PT (Adrian Hunter) - Introduce multiple debug variables control (Jiri Olsa) - Add callchain and additional sample information for python scripts (Joseph Schuchart) - More prep work to support Intel PT: (Adrian Hunter) - Polishing 'script' BTS output - 'inject' can specify --kallsym - VDSO is per machine, not a global var - Expose data addr lookup functions previously private to 'script' - Large mmap fixes in events processing - Include standard stringify macros in power pc code (Sukadev Bhattiprolu) Tooling cleanups: - Convert open coded equivalents to asprintf() (Andy Shevchenko) - Remove needless reassignments in 'trace' (Arnaldo Carvalho de Melo) - Cache the is_exit syscall test in 'trace) (Arnaldo Carvalho de Melo) - No need to reimplement err() in 'perf bench sched-messaging', drop barf(). (Davidlohr Bueso). - Remove ev_name argument from perf_evsel__hists_browse, can be obtained from the other parameters. (Jiri Olsa) Tooling fixes: - Fix memory leak in the 'sched-messaging' perf bench test. (Davidlohr Bueso) - The -o and -n 'perf bench mem' options are mutually exclusive, emit error when both are specified. (Davidlohr Bueso) - Fix scrollbar refresh row index in the ui browser, problem exposed now that headers will be added and will be allowed to be switched on/off. (Jiri Olsa) - Handle the num array type in python properly (Sebastian Andrzej Siewior) - Fix wrong condition for allocation failure (Jiri Olsa) - Adjust callchain based on DWARF debug info on powerpc (Sukadev Bhattiprolu) - Fix a risk for doing free on uninitialized pointer in traceevent lib (Rickard Strandqvist) - Update attr test with PERF_FLAG_FD_CLOEXEC flag (Jiri Olsa) - Enable close-on-exec flag on perf file descriptor (Yann Droneaud) - Fix build on gcc 4.4.7 (Arnaldo Carvalho de Melo) - Event ordering fixes (Jiri Olsa)" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (123 commits) Revert "perf tools: Fix jump label always changing during tracing" perf tools: Fix perf usage string leftover perf: Check permission only for parent tracepoint event perf record: Store PERF_RECORD_FINISHED_ROUND only for nonempty rounds perf record: Always force PERF_RECORD_FINISHED_ROUND event perf inject: Add --kallsyms parameter perf tools: Expose 'addr' functions so they can be reused perf session: Fix accounting of ordered samples queue perf powerpc: Include util/util.h and remove stringify macros perf tools: Fix build on gcc 4.4.7 perf tools: Add thread parameter to vdso__dso_findnew() perf tools: Add dso__type() perf tools: Separate the VDSO map name from the VDSO dso name perf tools: Add vdso__new() perf machine: Fix the lifetime of the VDSO temporary file perf tools: Group VDSO global variables into a structure perf session: Add ability to skip 4GiB or more perf session: Add ability to 'skip' a non-piped event stream perf tools: Pass machine to vdso__dso_findnew() perf tools: Add dso__data_size() ...
