A proposed set of kernel patches makes it possible to map anonymous MAP_SHARED mappings into the IPA space of a virtual machine with MTE enabled. With these patches we can use most features of crosvm with the exception of pmem which relies on being able to make file mappings in the IPA space. Therefore, we make MTE an opt-in feature via the --mte command line argument and forbid specifying --mte together with --pmem-device or --rw-pmem-device.
