Subject: [PATCH 0/3] KVM: SVM: Clean up SEV-ES save area management

Clean up KVM's handling of the SEV-ES host save area, and opportunistically
add a helper to dedup code for converting an SME-tweaked PA back into its
struct page.

Sean Christopherson (3):
  KVM: SVM: Add a helper to convert a SME-aware PA back to a struct page
  KVM: SVM: Add host SEV-ES save area structure into VMCB via a union
  KVM: SVM: Track the per-CPU host save area as a VMCB pointer
