SubjectRe: [PATCH for 2.5] preemptible kernel

Nope, it is a fundamental problem with such kernel pre-emption
schemes. As a result, it would also break our big-reader locks
(see include/linux/brlock.h).

Basically, anything which uses smp_processor_id() would need to
be holding some lock so as to not get pre-empted.
