Ok, I'll do that in a second.

Btw, another heads-up: you know how I'm regularly testing
Linus+tip/master - well, I started seeing some strange lockups on my
workstation with -rc7 + tip from two days ago. And the box wouldn't
resume properly, the last line it would print is:

"Disabling non-boot CPUs ..."

and then hang. I've backed-out tip/master and it seems to work so it has
to be some interaction caused by something in tip. I haven't been able
to put my finger on it though but I'll watch it and try to trigger it on
my other boxes.

Thanks.
