From 005f8eee6f3c8173e492d7bd4d51bda990eb468b Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 26 Mar 2009 15:25:01 +0100 Subject: [PATCH] [S390] cpumask: use mm_cpumask() wrapper 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).
