Applied to kvm-x86 svm, thanks!

[1/7] KVM: SVM: Make svm_x86_ops globally visible, clean up on-HyperV usage
      https://github.com/kvm-x86/linux/commit/44bfe1f0490d
[2/7] KVM: SVM: Move x2AVIC MSR interception helper to avic.c
      https://github.com/kvm-x86/linux/commit/eb44ea6a7aac
[3/7] KVM: SVM: Update "APICv in x2APIC without x2AVIC" in avic.c, not svm.c
      https://github.com/kvm-x86/linux/commit/a9095e4fc436
[4/7] KVM: SVM: Always print "AVIC enabled" separately, even when force enabled
      https://github.com/kvm-x86/linux/commit/ce4253e21fa8
[5/7] KVM: SVM: Don't advise the user to do force_avic=y (when x2AVIC is detected)
      https://github.com/kvm-x86/linux/commit/ad65dca2ca4c
[6/7] KVM: SVM: Move global "avic" variable to avic.c
      https://github.com/kvm-x86/linux/commit/b14665353162
[7/7] KVM: SVM: Enable AVIC by default for Zen4+ if x2AVIC is support
      https://github.com/kvm-x86/linux/commit/ca2967de5a5b
