From: Jan Beulich Date: Tue, 11 Mar 2008 10:30:25 +0000 (+0100) Subject: x86: adjust enable_NMI_through_LVT0() X-Git-Tag: v2.6.24.4~58 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=41abba651b51394ae1119ac26bd1dd2e31bc2dc0;p=thirdparty%2Fkernel%2Fstable.git 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).
