From 41abba651b51394ae1119ac26bd1dd2e31bc2dc0 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 11 Mar 2008 11:30:25 +0100 Subject: [PATCH] x86: adjust enable_NMI_through_LVT0() commit e94271017f0933b29362a3c9dea5a6b9d04d98e1 Its previous use in a call to on_each_cpu() was pointless, as at the time that code gets executed only one CPU is online. Further, the function can be __cpuinit, and for this to work without CONFIG_HOTPLUG_CPU setup_nmi() must also get an attribute (this one can even be __init; on 64-bits check_timer() also was lacking that attribute).
