Subject: [PATCH 0/4] x86: Cleanup and extend computing computing API

Updates for CC API:
 - Fix for HyperV when AMD SME/SEV disabled;
 - New home for CC code: arch/x86/coco;
 - Explicitly declare vendor of CC platform;
 - New cc_mkenc() and cc_mkdec();

Kirill A. Shutemov (4):
  x86/hyperv: Add missing ARCH_HAS_CC_PLATFORM dependency
  x86: Rename cc_platform.c to arch/x86/coco/core.c
  x86/coco: Explicitly declare type of confidential computing platform
  x86/coco: Add API to handle encryption mask
