Subject: [PATCH 0/3] Enumerate TME and PCONFIG
Date:   Wed, 31 Jan 2018 12:15:06 +0300

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.

Kirill A. Shutemov (3):
  x86/cpufeatures: Add Intel Total Memory Encryption cpufeature
  x86/tme: Detect if TME and MKTME is activated by BIOS
  x86/cpufeatures: Add Intel PCONFIG cpufeature
