I believe we should be much more aggressive about putting code into generic
locations, especially when there is nothing hardware specific to it.

As we can see from all the mess regarding interrupt controllers, PCI busses
or dma mapping, most of the smaller architectures get it wrong when they
have to deal with these things, so when we have a common implementation,
it's much easier to make sure we only have the bugs once and don't get
incompatible interfaces.
