Hmmm, upon closer inspection I found out this patch had *not* been in
what I extracted from the linux-2.4 bitkeeper tree, so my report was
probably not of much value. I'll retest tomorrow with the above applied.
Sorry for the confusion <-- I still can't see the patch in the listings
at http://linux.bkbits.net:8080/linux-2.4/

The patch I used is
http://www.dragon.cz/~kala/patch-2.4.19-pre8-sparcfixes-upto020523-1.gz
(I assembled it by hand using the bk web interface, looking up all sparc
related changes since -pre8.)
