Hi, all!

This is an assorted series of patches which aim is to make some further
basis for PCI passthrough on Arm support. The series continues the work
published earlier by Arm [1] and adds new helpers and clears the way for
vPCI changes which will follow.

RFC is at [2], [3]. Design presentation can be found at [4].

I have dropped some r-b's from Stefano as I touched some patches after
the review: most of those are minor cleanups, but still.

Thank you,
Oleksandr
