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
