Hi Ingo,
Please consider pulling, there are quite a few patches, but that is
because Adrian did the right thing and made his patches very granular, thanks
Adrian!

perf tests: Fix software clock events test setting maps (2015-09-15 11:04:49
-0300)
----------------------------------------------------------------
perf/urgent fixes:
User visible:
- 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)
