Here's a bugfix update to my previous patch.  I was mistakenly
using smp_call_function w/ interrupts disabled.  There's a definite
danger of deadlock under those circumstances.  I've attached a new
version of the last patch as well as an interdiff between the two.
Let me know if there are any other issues.  Thanks,

	Alex
