From 9e2f913df70b378379a358a44e7d286f7b765e8e Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 1 Jan 2009 10:12:14 +1030 Subject: percpu: fix percpu accessors to potentially !cpu_possible() cpus: m32r Impact: CPU iterator bugfixes Percpu areas are only allocated for possible cpus. In general, you shouldn't access random cpu's percpu areas.
