Oh but it looks like MAINTAINERS says I am :-)

Ok so from that perspective, I don't like it at all. You can try to
convince me otherwise but I don't think we need to introduce a
dependency to something like msi into the core remapper. It's already to
complex.

Why don't you move the powerpc bitmap allocator over to a generic
place ? I feel like it would be actually simpler but feel free to prove
me wrong.
