Eventually we'll need to look at how this interacts with kexec. A
kexec'd kernel will need to use the mapping already chosen by a
previous kernel, but that's an issue for another patch series.

FYI, this is exactly what Borislav has been tackling on x86 recently. It
would be nice if we could find one scheme that suits everyone.

Is this arm 32 or 64-bit? Because we haven't talked about 32-bit on x86
either. From skimming over the code, I'm not sure the same top-down
allocation and 1:1 mapping would work there. But I haven't looked hard
yet so I dunno.

This is arm 32. We'll be looking at arm 64 next.
