e121edced2 Change the GDT push logic
Instead of looking for a zero field, we now keep track of the next free index in a separate field. This avoids the bug that the high u64 of a pushed TSS descriptor is treated as empty.

9963961f35 Test the handler_with_error_code macro in a different way
We now take stack_frame as a immutable reference and we shouldn't write to a &. So the old test example (page faults as breakpoints) becomes even more hacky. Instead, we're now deliberately entering an endless page fault loop to check our iretq logic.

We have to map the P4 table recursively before setting paging - can't do this wherever we'd like.
