Subject: [PATCH 9/13] cpumask: use mm_cpumask() wrapper: mn10300


Makes code futureproof against the impending change to mm->cpu_vm_mask
(to be a pointer).

It's also a chance to use the new cpumask_ ops which take a pointer
(the older ones are deprecated, but there's no hurry for arch code).

Also change the actual arg name here to "mm" (which it is), not "task".
