From 4651fc56bad01d340844c5fbf1e1f817639208ab Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Wed, 9 Jun 2021 17:09:09 +0200 Subject: [PATCH] KVM: x86: Drop vendor specific functions for APICv/AVIC enablement Now that APICv/AVIC enablement is kept in common 'enable_apicv' variable, there's no need to call kvm_apicv_init() from vendor specific code. No functional change intended.
