I get this same error when trying to compile modules for stock 2.4.6. I have
no problems with 2.4.5 or any version previous.

>>>>>>background.c:57: `do_softirq_Rf0a529b7' undeclared (first use in \
>>>>>> this function)

except I get it in a different place...

It's not clear to me from the earlier posts... do I insert an include for
interrupt.h into cfi_probe.c or not?

I'm trying to compile mtd/cfi support on my laptop because I'm guessing I
want this in order to write ext2 filesystems onto CF type-1 flash cards via
a pcmcia-cf adapter.

though I'm only guessing about that, I really have no idea how to proceed on
that...

The purpose is to install precompiled / cross-compiled binaries for the sh3
processor and hopefully eventually run linux on an HP Jornada 548

maybe it would be easier to use the jornada to write to the cf card, if
there was only a "rawrite" or "dd" for WinCE out there somewhere...
