I'm not advocating anything similar for Linux, I'm just saying it's an
interesting thought experiment - what if the SMP-ness of a machine was
abstracted from the kernel proper? How much of the kernel really cares, or
really *should* care about SMP/UP?

Every spinlock :-) You'd have to either accept their overhead, or have
some way to nop out the instructions on uniprocessor boots. There
would still be the space overhead after such code patching.

I remember the Digital UNIX folks did something interesting in this
area. There should be a paper online somewhere.
