* feat: refactor memory management and integrate memblockRichard Qin2026-05-026-425/+735
| | | | | | | | | | | - Updated physical memory management (PMM) to utilize memblock for memory layout and frame allocation. - Enhanced the virtual memory manager (VMM) to allocate the frame map from memblock, ensuring it starts at the correct virtual address without relocation. - Improved frame allocation and deallocation functions to handle physical addresses more consistently. - Adjusted the slab allocator to correctly convert between physical and virtual addresses. - Refined page fault handling to ensure proper frame allocation and address translation. - Streamlined the initialization process for PMM and VMM, ensuring a more robust setup of memory structures.
