From 1ae4de23eddef465104277e79fa669bec7b3d288 Mon Sep 17 00:00:00 2001 From: Uros Bizjak Date: Sun, 2 Jun 2019 21:11:56 +0200 Subject: [PATCH] KVM: VMX: remove unneeded 'asm volatile ("")' from vmcs_write64 __vmcs_writel uses volatile asm, so there is no need to insert another one between the first and the second call to __vmcs_writel in order to prevent unwanted code moves for 32bit targets.
