Okay. I suppose the only other option is to make "physical_start" a variable passed in by the bootloader so that it could make a runtime decision? Ie, place us at min(top_of_mem, 4G) if it cared to. I just grepped for PHYSICAL_START and this didn't look _too_ bad.No can do. You'd have to make the kernel relocatable, and do load-time fixups. Very invasive.
Yes, that wasn't too smart. I believe in principe most of it _could_ be done via some pagetable trickery though, with the kernel still at a fixed virtual address?
