ladybird/Kernel
History
Andreas Kling 683185e4aa MM: Allocate page tables from a separate set of physical pages. 
The old approach only worked because of an overpermissive accident.
There's now a concept of supervisor physical pages that can be allocated.
They all sit in the low 4 MB of physical memory and are identity mapped,
shared between all processes, and only ring 0 can access them.
