This patchset enumerates two features required for Multi-Key Total Memory Encryption enabling[1].
Apart from trivial cpufeatures bits, the patchset enumerates how many bits from physical address are claimed for encryption key ID. This may be critical as we or guest VM must not use these bits for physical address. Please review and consider applying.
