Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf changes from Ingo Molnar: "Lots of changes: - (much) improved assembly annotation support in perf report, with jump visualization, searching, navigation, visual output improvements and more. - kernel support for AMD IBS PMU hardware features. Notably 'perf record -e cycles:p' and 'perf top -e cycles:p' should work without skid now, like PEBS does on the Intel side, because it takes advantage of IBS transparently. - the libtracevents library: it is the first step towards unifying tracing tooling and perf, and it also gives a tracing library for external tools like powertop to rely on. - infrastructure: various improvements and refactoring of the UI modules and related code - infrastructure: cleanup and simplification of the profiling targets code (--uid, --pid, --tid, --cpu, --all-cpus, etc.) - tons of robustness fixes all around - various ftrace updates: speedups, cleanups, robustness improvements. - typing 'make' in tools/ will now give you a menu of projects to build and a short help text to explain what each does. - ... and lots of other changes I forgot to list. The perf record make bzImage + perf report regression you reported should be fixed." * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (166 commits) tracing: Remove kernel_lock annotations tracing: Fix initial buffer_size_kb state ring-buffer: Merge separate resize loops perf evsel: Create events initially disabled -- again perf tools: Split term type into value type and term type perf hists: Fix callchain ip printf format perf target: Add uses_mmap field ftrace: Remove selecting FRAME_POINTER with FUNCTION_TRACER ftrace/x86: Have x86 ftrace use the ftrace_modify_all_code() ftrace: Make ftrace_modify_all_code() global for archs to use ftrace: Return record ip addr for ftrace_location() ftrace: Consolidate ftrace_location() and ftrace_text_reserved() ftrace: Speed up search by skipping pages by address ftrace: Remove extra helper functions ftrace: Sort all function addresses, not just per page tracing: change CPU ring buffer state from tracing_cpumask tracing: Check return value of tracing_dentry_percpu() ring-buffer: Reset head page before running self test ring-buffer: Add integrity check at end of iter read ring-buffer: Make addition of pages in ring buffer atomic ...
