From 365acf15d36345bd3b3df1f1f5dba76156c95dc7 Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Fri, 25 Mar 2022 19:11:13 -0300 Subject: spapr: Move nested KVM hypercalls under a TCG only config. These are the spapr virtual hypervisor implementation of the nested KVM API. They only make sense when running with TCG.
