From 4cb5b77eecb0ccb2fa66f33ac6936680bbc41552 Mon Sep 17 00:00:00 2001 From: Uros Bizjak Date: Tue, 23 Jun 2020 20:34:39 +0200 Subject: [PATCH] KVM: x86: Use VMCALL and VMMCALL mnemonics in kvm_para.h Current minimum required version of binutils is 2.23, which supports VMCALL and VMMCALL instruction mnemonics. Replace the byte-wise specification of VMCALL and VMMCALL with these proper mnemonics.
