Linux 2.4.19pre9-ac3

I got this error while I was compiling 2.4.19-pre9-ac3 + preempt:

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,
