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).
