Subject: cpumask: use mm_cpumask() wrapper: kernel/fork.c
X-Git-Tag: v2.6.30-rc1~604^2~6
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=9489424454c93f4d225d7af47978f8c7e84bf4d4;p=linux.git

cpumask: use mm_cpumask() wrapper: kernel/fork.c

Impact: futureproof

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.
