If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Thu Nov 9 09:48:01 CET 2017 From: Frederic Weisbecker <fweisbec(a)gmail.com> Date: Thu, 5 Jan 2017 18:11:41 +0100 Subject: sched/cputime, powerpc32: Fix stale scaled stime on context switch From: Frederic Weisbecker <fweisbec(a)gmail.com> [ Upstream commit 90d08ba2b9b4be4aeca6a5b5a4b09fbcde30194d ] On context switch with powerpc32, the cputime is accumulated in the thread_info struct. So the switching-in task must move forward its start time snapshot to the current time in order to later compute the delta spent in system mode. This is what we do for the normal cputime by initializing the starttime field to the value of the previous task's starttime which got freshly updated. But we are missing the update of the scaled cputime start time. As a result we may be accounting too much scaled cputime later. Fix this by initializing the scaled cputime the same way we do for normal cputime.

This is more than suboptimal since it partially doesn't work. For the fake NUMA case topology information is still considered and scheduling domains will be created based on this.
