Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
- Fix segfault pressing -> in 'perf top' with no hist entries. (Wang Nan)
E.g:
perf top -e page-faults --pid 11400 # 11400 generates no page-fault
- Fix propagation of thread and cpu maps, that got broken when doing incomplete
changes to better support events with a PMU cpu mask, leading to Intel PT to
fail with an error like:
$ perf record -e intel_pt//u uname
Error: The sys_perf_event_open() syscall returned with
22 (Invalid argument) for event (sched:sched_switch).
Because intel_pt adds that sched:sched_switch evsel to the evlist after the
thread/cpu maps were propagated to the evsels, fix it. (Adrian Hunter)
