Helper to abstract vma handling in media layer

This pull request merged Jan's vb2/mm patches to abstract vma handling.

See http://www.spinics.net/lists/linux-media/msg89653.html for more info.

It's the same pull request as from May 25th, but with an additional patch that puts get_vaddr_frames() behind a config option (requested by Andrew Morton).

Regards,

Hans
