Subject: [PATCH] i386 cpuid: Misc cpuinit annotations


cpuid_class_cpu_callback() is callback function of a CPU hotplug
notifier_block (that is already marked as __cpuinitdata). Therefore
it can safely be marked as __cpuinit.

cpuid_device_create() is only referenced from other functions that
are __cpuinit or __init. So it can also be safely marked __cpuinit.
