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. ]
