Zhang Junyang	141fbeaf0c	Optimize the page table implementation using the frame metadata ... This PR also refactored the page table cursor, distinguishing `Cursor` from `CursorMut`, and split a lot of functions to reduce dynamic condition checking. There are also other sanitizations performed, including refactoring PTE's `is_huge` API to `is_last`, hardening tracked mapping checks, and making `VmFrame` any size.	2024-06-03 22:16:02 +08:00
Zhang Junyang	69d464fc6b	Use metadata to track VmFrames ... In this commit, the frame metadata storage schema is implemented. The bootstrap process is refactored and a boot page table is introduced to perform early stage metadata mapping. The metadata is then used to track `VmFrame`s instead of the former `Arc` approach.	2024-06-03 22:16:02 +08:00
