If anyone has any objections, please let us know. --------------------- From: Jan Beulich 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).
