FWIW, there is code in the tree (even was in 1.2 I think) that is
supposed to disable any CPU but the first (well, actually, it just
makes sure that all interrupts go exclusively to the master
CPU). However, things have changed a lot since I wrote that (notably,
the cpu-state abstraction stuff went in, and a bunch of preliminary MP
stuff got merged), so I'm not sure what the current state of that code
is. The old code was actually never tested, but should have worked at
least if the system was booted from CPU0 (not clear what would happen
if it were booted from another CPU...)
