Functions
PtrResult< vmap_t >	mm_get_free_vaddr_locked (MMContext *mmctx, size_t n_pages, ptr_t base_vaddr, bool exact)
	Gets npages unmapped free pages from a page table.
void	mm_map_kernel_pages (MMContext *mmctx, ptr_t vaddr, pfn_t pfn, size_t npages, VMFlags flags)
	Map a block of virtual memory to a block of physical memory.
PtrResult< vmap_t >	mm_map_user_pages (MMContext *mmctx, ptr_t vaddr, pfn_t pfn, size_t npages, VMFlags flags, vmap_type_t type, vmap_content_t content, bool exact)
void	mm_replace_page_locked (MMContext *ctx, ptr_t vaddr, pfn_t pfn, VMFlags flags)
	Replace the mappings of a page with a new physical frame.
PtrResult< vmap_t >	mm_clone_vmap_locked (const vmap_t *src_vmap, MMContext *dst_ctx)
	Remap a block of virtual memory from one page table to another, i.e. copy the mappings.
bool	mm_get_is_mapped_locked (MMContext *mmctx, ptr_t vaddr)
	Get if a virtual address is mapped in a page table.
void	mm_flag_pages_locked (MMContext *ctx, ptr_t vaddr, size_t npages, VMFlags flags)
