This is v2 patch set for enabling per-core RAPL counters through
energy-cores event on RAPL PMU. Added RFC tag because a new patch is
added and this additional patch may need clarification from the
community.

While enabling this support with v1 patch [1], Stephane reported an
issue where for the first reading of energy-cores event for every core was
invalid [2]. This issue is addressed with patch 1 of this series. There
is no change in patch 2.

- Added new patch to fix the issue reported by Stephane
