Subject: i386: smp-alt-once option is only useful with HOTPLUG_CPU
X-Git-Tag: v2.6.23-rc1~114
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=09488165d5cc795a90b789c5657b1cbd279beb16;p=linux-2.6-omap-h63xx.git

i386: smp-alt-once option is only useful with HOTPLUG_CPU

Hence remove its handling in the opposite case.
