From: Thomas Gleixner Date: Thu, 10 Mar 2016 11:54:16 +0000 (+0100) Subject: sched/migration: Move calc_load_migrate() into CPU_DYING X-Git-Tag: v4.7~408^2~11^2~5 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e9cd8fa4fcfd67c95db9b87c0fff88fa23cb00e5;p=platform%2Fkernel%2Flinux-amlogic.git sched/migration: Move calc_load_migrate() into CPU_DYING It really does not matter when we fold the load for the outgoing cpu. It's almost dead anyway, so there is no harm if we fail to fold the few microseconds which are required for going fully away.
