[PATCH RFC 20/22] i386: use global kvm_state in hyperv_enabled() check


From: Vitaly Kuznetsov
Subject: [PATCH RFC 20/22] i386: use global kvm_state in hyperv_enabled() check
Date: Fri, 4 Sep 2020 16:54:29 +0200

There is no need to use vCPU-specific kvm state in hyperv_enabled() check
and we need to do that when feature expansion happens early, before vCPU
specific KVM state is created.
