hi,
sending fixes for tools and libperf.
thanks,
jirka

Jiri Olsa (5):
tools: Add missing perf_event.h include
libperf: Use perf_cpu_map__nr instead of cpu_map__nr
libperf: Move cpu_map__empty to perf_cpu_map__empty
libperf: Move cpu_map__idx to perf_cpu_map__idx
libperf: Add perf_thread_map__nr/perf_thread_map__pid functions

We need perf_event.h include for 'struct perf_event_mmap_page'.

Switch the rest of the perf code to use perf_cpu_map__nr,
which is the same as current cpu_map__nr and remove
cpu_map__nr function.

So it's part of libperf library as one of basic functions
over struct perf_cpu_map object.
