Took me a while to find that... in moduleparam.h :)
Yeah, it probably makes sense to split it out, and probably add a
'uniquify' macro which properly appends __COUNTER__ to some string; PCI
fixup declarations could do with that too. I'll probably just add them
to stringify.h -- I don't think they each justify separate files of
their own. It's all just CPP magic.
Although I was actually going to drop DECLARE_BUILTIN_FIRMWARE. I'm not
doing that from C code at all any more -- it's all in asm. At this
point, it only really serves as documentation for that one patch in the
series (and yes, it's scary that such a construct really does give
people more of a clue what's going on).
