Merge branch 'perf-core-for-linus' of git://
Pull perf updates from Ingo Molnar: "Kernel side changes: - Ftrace is one of the last W^X violators (after this only KLP is left).

This requires a surprising amount of surgery, by Peter Zijlstra. - x86/AMD PMUs: add support for 'Large Increment per Cycle Events' to count certain types of events that have a special, quirky hw ABI (by Kim Phillips) - kprobes fixes by Masami Hiramatsu Lots of tooling updates as well, the following subcommands were updated: annotate/report/top, c2c, clang, record, report/top TUI, sched timehist, tests; plus updates were done to the gtk ui, libperf, headers and the parser" * 'perf-core-for-linus' of git:// (57 commits) perf/x86/amd: Add support for Large Increment per Cycle Events perf/x86/amd: Constrain Large Increment per Cycle events perf/x86/intel/rapl: Add Comet Lake support tracing: Initialize ret in syscall_enter_define_fields() perf header: Use last modification time for timestamp perf c2c: Fix return type for histogram sorting comparision functions perf beauty sockaddr: Fix augmented syscall format warning perf/ui/gtk: Fix gtk2 build perf ui gtk: Add missing zalloc object perf tools: Use %define api.pure full instead of %pure-parser libperf: Setup initial evlist::all_cpus value perf report: Fix no libunwind compiled warning break s390 issue perf tools: Support --prefix/--prefix-strip perf report: Clarify in help that --children is default tools build: Fix test-clang.cpp with Clang 8+ perf clang: Fix build with Clang 9 kprobes: Fix optimize_kprobe()/unoptimize_kprobe() cancellation logic tools lib: Fix builds when glibc contains strlcpy() perf report/top: Make 'e' visible in the help and make it toggle showing callchains perf report/top: Do not offer annotation for symbols without samples ...
