2020-01-06libperf: Move to tools/lib/perfJiri Olsa1-55/+0
Move libperf from its current location under tools/perf to a separate directory under tools/lib/. Also change various paths (mainly includes) to reflect the libperf move to a separate directory and add a new directory under MANIFEST.

2019-10-19libperf: Introduce perf_evlist__for_each_mmap()Jiri Olsa1-2/+3
Add the perf_evlist__for_each_mmap() function and export it in the perf/evlist.h header, so that the user can iterate through 'struct perf_mmap' objects. Add a internal perf_mmap__link() function to do the actual linking.

2019-10-10libperf: Adopt perf_mmap__put() function from tools/perfJiri Olsa1-12/+19
Move perf_mmap__put() from tools/perf to libperf. Once perf_mmap__put() is moved, we need a way to call application related unmap code (AIO and aux related code for eprf), when the map goes away. Add the perf_mmap::unmap callback to do that. The unmap path from perf is: perf_mmap__put (libperf) perf_mmap__munmap (libperf) map->unmap_cb -> perf_mmap__unmap_cb (perf) mmap__munmap (perf) Committer notes: Add missing linux/kernel.h to tools/perf/lib/mmap.c to get the BUG_ON definition.
