The intention was to backport only PATCH[5/5]: clockevents: Fix
cpu_down() race for hrtimer based broadcasting,
but this depends on commits upstream which did cleanup and
reorganization of code. However these commits cannot be cherry-picked as
is. There are a few minor changes upstream and hence these commits had
to be backported too. Reasons for backports are given below:
1. PATCH[1/5]: The upstream commit introduced a duplicate function which
was removed much later by commit:
9eed56e889d: clockevents: Clean up clockchips.h
We do not need to cherry-pick the entire above commit because the backport
was a simple one.
2. PATCH[3/5]: There are newer functions introduced upstream through
554ef3876c6: clockevents: Handle tick device's resume separately
Yet again we did not need to cherry pick the entire above commit,
firstly because it introduces significant new code, secondly because the
backport was a simple one.
3. PATCH[4/5]: The function clockevent_set_mode() was renamed to
clockevent_set_state() upstream by commit:
77e32c89a7: clockevents: Manage device's state separately for
the core
We do not need to cherry-pick this commit for the same reason as in (2).
This series needs to be applied on top of stable-4.0. A new series will
be sent out for stable-3.19.
