Thanks Keith.

I'm an experienced linux user, but a crappy kernel programmer :) Always good to have clarity.


OT - Just ready about "The Search for The Holy Grail" on Slashdot. Keep wanting to say: "Behind the rabbit?" Sorry... I'll go away now.

This is a different patch than the one I was aware of from the kml. Is
this preferred over the non-version symbol export? (Hope I didn't misunderstand that..) That one seemed to work well.


Both patches are mine.  It required about 10 emails between various
kernel hackers and digging into the more obscure bits of gcc to agree
on a method of exposing calls to exported symbols from __asm__ code.
The change to softirq.h is the correct mechanism, especially as you do
not have to run make mrproper after applying the patch, changing from
EXPORT_SYMBOL() to EXPORT_SYMBOL_NOVERS() requires make mrproper.
