From 0aa48468d00959c8a37cd3ac727284f4f7359151 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Mon, 21 May 2018 17:54:49 -0400 Subject: [PATCH] KVM/VMX: Expose SSBD properly to guests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The X86_FEATURE_SSBD is an synthetic CPU feature - that is it bit location has no relevance to the real CPUID 0x7.EBX[31] bit position. For that we need the new CPU feature name.
