Subject: [PATCH] Revert "target/i386: kvm: add VMX migration blocker"
This reverts commit d98f26073bebddcd3da0ba1b86c3a34e840c0fb8.
As is, it rejects libvirt managedsave and virt-manager snapshots
for default installed VMs on intel hosts. Upstream Paolo says that
the missing kernel bits are already queued up, and until then it's
fine to revert this.
