Subject: x86: remove nesting CONFIG_HOTPLUG_CPU
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2bd455dbfebfd632a8dcf1d3d1612737986fde0a;p=linux-beck.git

x86: remove nesting CONFIG_HOTPLUG_CPU

prefill_possible_map() is defined inside CONFIG_HOTPLUG_CPU,
so the nesting CONFIG_HOTPLUG_CPU is just redundant.
