You need to add a #define __HAVE_ARCH_MEMMOVE to
include/asm-alpha/string.h.

Also, your patch seems to be broken. Sometimes it doesn't copy enough.
I had the same bug in my hacked version, before I made it into a patch,
and it was something like:

while (count--) {
...
}

turning into

while (count -= 8) {
...
}

instead of

while (count) {
count -= 8;
...
}

I can't see any of that in that patch, but scrolling around with emacs,
sometimes an 'if' turns into a 'ff'. Linus, I've left you on the cc list
for this message so that you know not to apply the patch in the previous
one.

Tim.
