[PATCH 00/10] vtime: Delay cputime accounting to tick / context switch

From: Frederic Weisbecker
Date: Thu Jan 05 2017 - 12:14:09 EST


This version is a rebase on top of latest Linus tree which includes
the fix 8f2b468aadc ("s390/vtime: correct system time accounting").

Also a small change: I have moved account_system_index_scaled() to s390
in patch "s390/cputime: delayed accounting of system time" because it is
the only user of the function.

Thanks,
Frederic
