  x86/cc: Fix enum spelling to fix kernel-doc warnings (2025-11-25 09:17:13 +0100)

----------------------------------------------------------------
 - Largely cleanups along with a change to save XSS to the GHCB (Guest-Host
   Communication Block) in SEV-ES guests so that the hypervisor can determine
   the guest's XSAVES buffer size properly and thus support shadow stacks in
   AMD confidential guests

----------------------------------------------------------------
Ard Biesheuvel (1):
      x86/boot: Drop unused sev_enable() fallback

Borislav Petkov (AMD) (1):
      x86/coco/sev: Convert has_cpuflag() to use cpu_feature_enabled()

John Allen (2):
      x86/boot: Move boot_*msr helpers to asm/shared/msr.h
      x86/sev: Include XSS value in GHCB CPUID request

Randy Dunlap (1):
