InitRD: Use MMU::translate_physical_address instead of allocating VM
All checks were successful
continuous-integration/drone/push Build is passing
This one is a perfect candidate, since we're just mapping a fixed continuous range of physical memory to virtual memory.

This would leak memory, since we would never end up using them.

x86_64/MMU: Map all physical memory into the higher half instead of using recursive mapping
All checks were successful
continuous-integration/drone/pr Build is passing
This still has a few problems. Notably, we are not using huge pages for this mapping, which would be a lot more efficient.
Right now, used memory is 8.1 MiB at boot for a 256MiB system.
But after improving it, this system will be much better than recursive mapping.
fork() will be MUCH easier to implement, for example.

We do this by preserving timestamps when copying headers so CMake doesn't think they have changed.
