When the kernel is mapped into virtual address space
that is different than the physical address space,
the dynamic GDT generation uses the virtual addresses.
However, the GDT table is required at boot before
page table is loaded where the virtual addresses are
invalid. So make sure GDT generation is using
physical addresses.

Promote a handy and often-overlooked sys.exit() feature: Passing it a
string (or any other non-int object) prints it to stderr and exits with
status 1.
See the documentation at
https://docs.python.org/3/library/sys.html#sys.exit.
This indirectly prints some errors to stderr that previously went to
stdout.
