  x86/sev: Report MSR_AMD64_SEV in sysfs (2026-09-21 20:28:44 -0700)

----------------------------------------------------------------
- Report in sysfs which SEV confidential computing features are enabled in the
  environment so that related components like a SVSM can query them and do
  appropriate configuration

- Add support for a new AMD SEV instruction called RMPOPT which can be
  used to reduce the performance overhead of doing confidential guests'
  page ownership verification and the like. Work by Ashish Kalra

----------------------------------------------------------------
Ashish Kalra (5):
      x86/cpufeatures: Add X86_FEATURE_RMPOPT feature flag
      x86/sev: Disable CPU hotplug while SNP is active
      x86/sev: Initialize RMPOPT configuration MSRs
      x86/sev: Perform RMP optimizations asynchronously
      x86/sev: Do RMP optimizations on SNP guest shutdown
