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.
