I'll do that -- thanks!

Looks like linux-next still has plain spin_lock, not the irqsave variant.

Is this something that needs to be pushed to mainline and/or stable?

If it should go upstream, is this something that Freescale can do, or
should I try to put together a patch?  (I'd like to avoid having to do
it myself, because I'm carrying out-of-tree patches that I'd have to
port to linux-next before it'd be accepted there, I fear.)

Either way, I'll definitely report if it fixes the splat on my 3.9.7
system.

Thanks again!
