Subject: [VOYAGER] x86: use CONFIG_X86_SMP instead of CONFIG_SMP

CONFIG_SMP is used for features which work on *all* x86 boxes.
CONFIG_X86_SMP is used for standard PC like x86 boxes (for things like
multi core and apics)

i've applied your fix to tip/x86/urgent, as it's obviously correct in 
the current scheme of things, thanks!

but that needless build-time distinction should go away. We can now 
support a whole host of 'weird' SMP boxes via genapic and x86_quirks.
