Subject: [PATCH v1 0/4] Share common features between AMD SEV / TDX guest

Hi All,

Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious
hosts and some physical attacks. TDX has a lot of similarities to AMD SEV.
Features like encryption/decryption and string I/O unroll support can
be shared between these two technologies.

This patch set adds infrastructure changes required to share the code
between AMD SEV and TDX.

Kirill A. Shutemov (1):
  x86: Move common memory encryption code to mem_encrypt.c

Kuppuswamy Sathyanarayanan (3):
  x86/sev: Remove sev_enable_key usage in outs##bwl()/ins##bwl()
  x86/sev: Use CC_ATTR attribute to generalize string I/O unroll
  x86/sev: Rename mem_encrypt.c to mem_encrypt_amd.c
