[PATCH 0/3] KVM: s390: Enable AP instructions for pv-guests

[Steffen Eiden <seiden@xxxxxxxxxxxxx>]

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).
