[PATCH v5 14/17] i386: use global kvm_state in hyperv_enabled() check


From: Vitaly Kuznetsov
Subject: [PATCH v5 14/17] i386: use global kvm_state in hyperv_enabled() check
Date: Mon, 1 Mar 2021 14:51:00 +0100

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.
