I tried the same with HOTPLUG_CPU as well, to just say 

select X86_GENERICARCH

but problem was this didnt enforce the selection, i.e user still could go and revert
the selection made automatic for him, i.e go ahead and select X86_PC, and it would 
still leave the HOTPLUG_CPU=y around. I thought "depends" sort of forces the selection.

Maybe i didnt try correctly, if you have alternatives please do, actually even for 
HOTPLUG_CPU if this could be made automatic select, and at the same time enforced
strictly, thats great.

(for e.g i shoud;t be able to select X86_PC=y and leave CONFIG_HOTPLUG_CPU=y around)
