Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Ingo Molnar: "On the kernel side there's two x86 PMU driver fixes and a uprobes fix, plus on the tooling side there's a number of fixes and some late updates" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits) perf sched timehist: Fix invalid period calculation perf sched timehist: Remove hardcoded 'comm_width' check at print_summary perf sched timehist: Enlarge default 'comm_width' perf sched timehist: Honour 'comm_width' when aligning the headers perf/x86: Fix overlap counter scheduling bug perf/x86/pebs: Fix handling of PEBS buffer overflows samples/bpf: Move open_raw_sock to separate header samples/bpf: Remove perf_event_open() declaration samples/bpf: Be consistent with bpf_load_program bpf_insn parameter tools lib bpf: Add bpf_prog_{attach,detach} samples/bpf: Switch over to libbpf perf diff: Do not overwrite valid build id perf annotate: Don't throw error for zero length symbols perf bench futex: Fix lock-pi help string perf trace: Check if MAP_32BIT is defined (again) samples/bpf: Make perf_event_read() static uprobes: Fix uprobes on MIPS, allow for a cache flush after ixol breakpoint creation samples/bpf: Make samples more libbpf-centric tools lib bpf: Add flags to bpf_create_map() tools lib bpf: use __u32 from linux/types.h ...
