    Subject[PATCH 0/5] x86/sev: Fix SNP host late disable
    Date
    From: "Borislav Petkov (AMD)" <bp@alien8.de>

    Hi,

    the intention to track SNP host status with the CPU feature bit
    X86_FEATURE_SEV_SNP was all fine and dandy but that can't work if stuff
    needs to be disabled late, after alternatives patching - see patch 5.

    Therefore, convert the SNP status tracking to a cc_platform*() bit.

    The first two are long overdue cleanups.

    If no objections, 3-5 should go in now so that 6.9 releases fixed.

    Thx.

    Borislav Petkov (AMD) (5):
    x86/alternatives: Remove a superfluous newline in _static_cpu_has()
    x86/alternatives: Catch late X86_FEATURE modifiers
    x86/kvm/Kconfig: Have KVM_AMD_SEV select ARCH_HAS_CC_PLATFORM
    x86/cc: Add cc_platform_set/_clear() helpers
    x86/CPU/AMD: Track SNP host status with cc_platform_*()
