[patch 4/3] cpusets: memory_spread_user interleaves over allmems_allowed

[David Rientjes]

Instead of using current's mems_allowed, which may differ from the
mems_allowed of the cpuset being updated, the newmask passed to
mpol_rebind_mm() is used as the interleave mask in the
memory_spread_user case.
