Recent changes in linux/fs/block_dev.c unfortunately conflicted
with Linux as used on 64-bit Alpah (c.f.
http://www.azstarnet.com/~axplinux/ for a complete set of "axp-diffs").
I include below differences between Intel and axp versions of
block_dev.c from 2.0.30; they are neutral on Intel but surely
are important on Alpha.
If you use these patches, then declarations of block_read and
block_write in include/linux/fs.h also have to be adjusted
accordingly.
