Subjectmemmove() in 2.4.0-test12, alpha platform
Hello !

New (since test12) optimized memmove function seems to be broken
on alpha platform.

If dest and src arguments are misaligned, new memmove does wrong things.


example:

static char p[] = "abcdefghijklmnopkrstuvwxyz01234567890";
memmove(p + 2, p + 13, 17);
printk ("DEBUG: memmove test: %s\n", p);

produces:

DEBUG: memmove test: abyz0123tuvwxyz0123tuvwxyz01234567890


Old memmove variant didn't have this problem.

Thanks,
Alex.
