Thanks for doing these for the mainline rc's too. I've seen them for
the stable kernels, but it's lovely to see it for rc1.

Ahh. Does it just need a

EXPORT_SYMBOL_GPL(irq_check_status_bit);

in there? Because it looks like at least irq_is_percpu() and
irq_is_percpu_devid() are used in drivers/perf/ and can apparently be
modules.

Thomas?

Ok, I won't worry about that one.

Same.

Looks like Kalesh is looking at it.

I don't think that was supposed to matter at all on parisc, but
clearly something bad happened.

parsic doesn't even enable HAVE_MOVE_PMD, much less the new
HAVE_MOVE_PUD. Strange.
