Subject[PATCHv3 0/3] Share common features between AMD SEV / TDX guest
Date
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.

v3:
- Adjust wording in 1/3 based on Tom's feedback.
- Tested-by from Tom.
v2:
- Squash first two patches
- Rename print_amd_mem_encrypt_feature_info() to print_mem_encrypt_feature_info().
It will report TDX feature too.

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

Kuppuswamy Sathyanarayanan (2):
x86/sev: Use CC_ATTR attribute to generalize string I/O unroll
x86/sev: Rename mem_encrypt.c to mem_encrypt_amd.c
