A few of the above was easy to fix. See patch below.
But alpha plays strange tricks with WEAK and ALIAS and __initdata for alpha_mv (and the cousins *_mv).
This is the reasons for most of the warnings - and I did not look deep enough to really understand
the logic (and thereby to come up with a fix).
Maybe the ALPHA maintainers can help?
