bool FreeLocked (uint64_t addr)Though this address space does not support allocations, this needs to be implemented
to avoid errors from when a gpu mapping is released and attempts to call |FreeLocked|.

should be cache coherent with the GPU.

bool Insert (gpu_addr_t addr, magma::PlatformBusMapper::BusMapping * bus_mapping, uint64_t offset_bytes, uint64_t length_bytes, uint64_t flags)offset_bytes and length_bytes must be multiples of both the CPU page size and the GPU page

fit::result<MapError> Map (uint64_t vaddr, uint64_t size, uint64_t paddr, MapSettings settings)Maps the provided page-aligned physical memory region at the given virtual
address.
If execute-only access is requested and the hardware does not support
this, the permissions will be fixed up as RX.
If the requested virtual address range is in the upper address space, the
settings will also be fixed up to be global (as these ranges are intended
for permanent kernel mappings).

void SetPageTableAllocationBounds (ktl::optional<uint64_t> low, ktl::optional<uint64_t> high)Restricts the memory out of which page tables may be allocated. A bound of
ktl::nullopt indicates that the corresponding default bound on the global
memalloc::Pool should be respected instead (i.e., the default behaviour).
This method may be called before Init() in order to ensure that root page
allocation respects these bounds as well.
In a nebulous period of early boot on x86-64, we have no guarantees on
what memory is mapped beyond our load image; in that case we must restrict
the allocation of fresh mappings out of that load image, which is where
this method comes in handy.

template <typename... Args>void Init (Args &&... args)Initializes the address space, allocating the root page table(s), and

ArchCreatePagingState().
