From 56f8ba83a52b9f9e3711eff8e54168ac14aa288f Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 24 Sep 2009 09:34:49 -0600 Subject: cpumask: use mm_cpumask() wrapper: arm 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).
