Since I have a different gcc than yours (and I'm not going to compile
my own), have you posted your broken .s file anywhere? In fact, with
the noinline (and the removal of the "+m" thing - iow just the patch
you tried), what does just the "i8k_smm" function assembly look like
for you after you've done a "make drivers/char/i8k.s"?
If the asm just doesn't exist AT ALL, that's just odd. Because every
single call-site of i8k_smm() clearly looks at the return value. So
the volatile really shouldn't make any difference from that
standpoint. Odd.
