 - [ ] Update the kernel to correctly setup the GDT
 - [ ] Create a physical memory allocator and mapper. The kernel should live in the upper last gigabyte of virtual memory. It should support different zones (e.g.: `SUB_16M`, `DEFAULT`, ...) These zones describe the region of memory that memory should be allocated in. If it is not possible to allocate in that region (because it is full, or has 0 capacity to begin with), it should fallback to another zone.
 - [ ] Create a paging subsystem. It should allow drivers to allocate and deallocate pages at will.
