17 hourskern/amd64: mmu: Add mmu_free_vas() to cleanup VASIan Moffett
Introduce a new resource deallocation function that destroys a specified virtual address space. Signed-off-by: Ian Moffett <ian@osmora.org>
38 hourskern/amd64: mmu: Condence update into one line + fixIan Moffett
Condence the page table write into a single line and point the next table as a virtual address Signed-off-by: Ian Moffett <ian@osmora.org>

3 daysos/amd64: Make MMU header standard per archIan Moffett
Lunos's virtual memory system is split into two parts, the machine dependent MMU layer and the machine independent layer. The MMU side exposes a standard bridge header that allows the MI layer to interface with the MD layer. Signed-off-by: Ian Moffett <ian@osmora.org>

4 dayskern: vm: Implement page mapping and VASesIan Moffett
This commit implements an interface to allow other parts of Lunos to talk to the MMU: - Added the 'vas' structure as the virtual address space - Added MMU specific prot flags - Added mmu_map_single() to map pages - Added mmu_this_vas() to grab the current VAS ...
