That is a thinko in the preempt patch, not -ac... don't bother Alan with
it.
There is a new version of the patch up at the usual place which is
fixed. Or in smp.c just replace
cpu = get_cpu();
with
preempt_disable();
cpu = smp_processor_id();
and replace
put_cpu();
with
preempt_enable();
Sincerely,
Robert Love
