Hi, all!

While working on vPCI series [1] I have created number of patches that
either add some useful helpers or serve as the ground for the upcoming
vPCI changes or both.

To ease the task of reviewing the bigger vPCI series I am sending these
now with the hope they can be accepted.

I would like to thank Roger and Jan for providing valuable comments and
ideas, some of which have materialized here.

Thank you,
Oleksandr

Btw, while I'll let Roger judge for the latter two, for the former
two while I appreciate you breaking this out from the larger series
I'm not convinced these will want committing without a user
appearing at least in close succession. Hence also why so far I
didn't commit patch 1, which as per its tags could have been put in
already.
