thank you

I thought they might come useful to others playing with vmap_areas, I'll resubmit them anyway with the protected memory set.
But I was also hoping to get some more review, especially for the second, which had not received any definitive ACK/NACK, till now.
So, I'm also ok if they can be merged once the others are ACK'ed.
