Firstly, yes: I would mark the region as reserved or remove it completely,
rather than marking it with a newly-invented type code. Secondly I would
think you only need to modify boot_e820, probably using the helper function
reserve_in_boot_e820(), because that will suffice to hide the memory from
the normal memory allocator. And that's all you're trying to do, right?
