Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next
Pull perf updates from Ingo Molnar: "The tooling changes maintained by Jiri Olsa until Arnaldo is on vacation: User visible changes: - Add -F option for specifying output fields (Namhyung Kim) - Propagate exit status of a command line workload for record command (Namhyung Kim) - Use tid for finding thread (Namhyung Kim) - Clarify the output of perf sched map plus small sched command fixes (Dongsheng Yang) - Wire up perf_regs and unwind support for ARM64 (Jean Pihet) - Factor hists statistics counts processing which in turn also fixes several bugs in TUI report command (Namhyung Kim) - Add --percentage option to control absolute/relative percentage output (Namhyung Kim) - Add --list-cmds to 'kmem', 'mem', 'lock' and 'sched', for use by completion scripts (Ramkumar Ramachandra) Development/infrastructure changes and fixes: - Android related fixes for pager and map dso resolving (Michael Lentine) - Add libdw DWARF post unwind support for ARM (Jean Pihet) - Consolidate types.h for ARM and ARM64 (Jean Pihet) - Fix possible null pointer dereference in session.c (Masanari Iida) - Cleanup, remove unused variables in map_switch_event() (Dongsheng Yang) - Remove nr_state_machine_bugs in perf latency (Dongsheng Yang) - Remove usage of trace_sched_wakeup(.success) (Peter Zijlstra) - Cleanups for perf.h header (Jiri Olsa) - Consolidate types.h and export.h within tools (Borislav Petkov) - Move u64_swap union to its single user's header, evsel.h (Borislav Petkov) - Fix for s390 to properly parse tracepoints plus test code (Alexander Yarygin) - Handle EINTR error for readn/writen (Namhyung Kim) - Add a test case for hists filtering (Namhyung Kim) - Share map_groups among threads of the same group (Arnaldo Carvalho de Melo, Jiri Olsa) - Making some code (cpu node map and report parse callchain callback) global to be usable by upcomming changes (Don Zickus) - Fix pmu object compilation error (Jiri Olsa) Kernel side changes: - intrusive uprobes fixes from Oleg Nesterov. Since the interface is admin-only, and the bug only affects user-space ("any probed jmp/call can kill the application"), we queued these fixes via the development tree, as a special exception. - more fuzzer motivated race fixes and related refactoring and robustization. - allow PMU drivers to be built as modules. (No actual module yet, because the x86 Intel uncore module wasn't ready in time for this)" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (114 commits) perf tools: Add automatic remapping of Android libraries perf tools: Add cat as fallback pager perf tests: Add a testcase for histogram output sorting perf tests: Factor out print_hists_*() perf tools: Introduce reset_output_field() perf tools: Get rid of obsolete hist_entry__sort_list perf hists: Reset width of output fields with header length perf tools: Skip elided sort entries perf top: Add --fields option to specify output fields perf report/tui: Fix a bug when --fields/sort is given perf tools: Add ->sort() member to struct sort_entry perf report: Add -F option to specify output fields perf tools: Call perf_hpp__init() before setting up GUI browsers perf tools: Consolidate management of default sort orders perf tools: Allow hpp fields to be sort keys perf ui: Get rid of callback from __hpp__fmt() perf tools: Consolidate output field handling to hpp format routines perf tools: Use hpp formats to sort final output perf tools: Support event grouping in hpp ->sort() perf tools: Use hpp formats to sort hist entries ...
