From 7c3bab189c16a21742172b09979fd84c13698202 Mon Sep 17 00:00:00 2001 From: Chao Peng Date: Tue, 21 Feb 2017 03:50:01 -0500 Subject: KVM: VMX: use correct vmcs_read/write for guest segment selector/base commit 96794e4ed4d758272c486e1529e431efb7045265 upstream. Guest segment selector is 16 bit field and guest segment base is natural width field. Fix two incorrect invocations accordingly. Without this patch, build fails when aggressive inlining is used with ICC.
