Subject: cpumask: use mm_cpumask() wrapper: um
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fa40699b975131028a61aa8e095b0b17f350da40;p=linux-beck.git

cpumask: use mm_cpumask() wrapper: um

Makes code futureproof against the impending change to mm->cpu_vm_mask.

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).
