Merge tag 'v3.10' into sched/core
Merge in a recent upstream commit: c2853c8df57f include/linux/math64.h: add div64_ul() because: 72a4cf20cb71 sched: Change cfs_rq load avg to unsigned long relies on it. [ We don't rebase sched/core for this, because the handful of followup commits after the broken commit are not behavioral changes so are unlikely to be needed during bisection. ] Signed-off-by: Ingo Molnar <mingo@kernel.org>
