Ard Biesheuvel f2509d6d3e ArmVirtPkg: restrict mapping attributes of normal memory to EFI_MEMORY_WB ... In general, on an ARM system, mapping normal memory as device memory may have unintended side effects, given that unaligned accesses or loads and stores with special semantics (e.g., load/store exclusive) may fault or may not work as expected. Under KVM, the situation is even worse, since the host may not expect the guest to perform uncached accesses, and so writes to such an uncached region may get lost completely. Since the only safe mapping type under KVM is EFI_MEMORY_WB, remove all other memory type attributes.
