Subject: [PATCH 0/3] KVM: SVM: Clean up LBRv MSRs handling

Eliminate dead KVM_BUG() code in SVM's LBR MSRs virtualization by
refactoring the code to completely remove any need for a KVM_BUG(), and
clean up a few others pieces of related code.

Sean Christopherson (3):
  KVM: SVM: Fix dead KVM_BUG() code in LBR MSR virtualization
  KVM: SVM: Clean up handling of LBR virtualization enabled
  KVM: SVM: Use svm_get_lbr_vmcb() helper to handle writes to DEBUGCTL
