Subject: [PATCH 0/7] cputime: A few tickless cputime accounting fixes and improvements

The first two patches from Hiroshi Shimamoto are fixes to be backported.
Although it's debatable whether the 2nd patch needs backport.

The patches that follow are further fixes and cleanups and the last
one is an optimization.
