This series enables general KVM support for AP pass-through for Secure Execution guests (pv-guests).
To enable AP inside pv-guests two things have to be done/considered: 1) set corresponding flags in the Create Secure Configuration UVC ifi firmware supports AP for pv-guests (patch 3). 2) enable/disable AP in pv-guests if the VMM wants this (patch 2).
