Subject: [BUG] kernel BUG at arch/x86/kernel/tlb_32.c:130!

I was using mmotm 2009-01-16-16-18, and I ran into this BUG,
the line is:
	BUG_ON(cpumask_empty(cpumask));

I suspect it is caused by:

commit 4595f9620cda8a1e973588e743cf5f8436dd20c6
Author: Rusty Russell <rusty@...tcorp.com.au>
Date:   Sat Jan 10 21:58:09 2009 -0800

    x86: change flush_tlb_others to take a const struct cpumask

    Impact: reduce stack usage, use new cpumask API.
