[PATCH 0/5] perf tools: Clean up cpu map handling for system-wide evsel (v3)

[Namhyung Kim]

Hello,

The system-wide evsel has a cpu map for all (online) cpus regardless
of user requested cpus.  But the cpu map handling code has some
special case for it and I think we can cleanup the code by making sure
that such a evsel has a proper cpu/thread maps from the beginning.
This patches should not cause any change in the behavior.

Changes from v2:
 * build evlist->core.all_cpus from the beginning  (Adrian)

Changes from v1:
 * use evlist->core.needs_map_propagation field
 * add Reviewed-by from Adrian

You can get the code from 'perf/cpumap-update-v3' branch in

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
