Hmm. I'm a bit doubtful this will work for other architectures
as arm64 at least has two sets of memblocks and the holes probably
want to go in memblock.reserved rather than in memblock.memory.
I think we would want to reflect where the extra memblks was added.

However. I'm not 100% sure on what that ends up like as I've not
written an appropriate numa_fill_memblks() yet, so I guess for
now it's fine here, and maybe it will get pushed into the arch
specific code when a second architecture implements numa_fill_memblks()
if some architectures want to return more detailed info.

So, I've argued myself around to

p.s. Unrelated whitespace change but I guess can cope with that...

This one still feels too verbose to me, can it not be gleaned from other
startup messages?
