How about the attached changes?
I had to put in special handling for comments of the form:
These aren't exported outside the kernel to avoid name space clashes
because they invariably occur in the wrong section (ie. they would normally
end up in the UAPI side).
I consulted Thomas Gleixner about irqnr.h. He says it doesn't matter if that
one comment gets lost. Besides, something like that can be added back later,
perhaps in a better place (it doesn't look like it's in the right place now).
