Interesting... Perhaps you could send me your "bad" kernel vmlinux or
raid456.ko file;

	I've narrowed it a bit: the problem arises only when "-Os" is being used.

Built-in is fine.  I need the vmlinux file, though, not bzImage.

	Ok, it's compiling right now. vmlinux is pretty huge, so I guess it'd
be better to upload it to an ftp.

It probably is.  My side can handle large emails, but yours might not
(and, obviously, don't send it to the list.)

It sort of makes sense that -Os would break this stuff.  For newer gccs,
it would be better to use SSE2 intrinsics rather than inline assembly.
The problem is that it breaks older gcc.
