Subject: [PATCH] x86/KVM: Fix incorrect SSBD bit in kvm_cpuid_7_0_edx_x86_features
Date: Fri, 25 May 2018 13:16:24 -0400 [thread overview]
Message-ID: <1527268584-752-1-git-send-email-longman@redhat.com> (raw)
As the SSBD bit in kvm_cpuid_7_0_edx_x86_features has been renamed to
SPEC_CTRL_SSBD in the commit 52817587e706 ("x86/cpufeatures: Disentangle
SSBD enumeration"). The corresponding name change needed to be made in
the KVM code as well.
Fixes: 52817587e706 ("x86/cpufeatures: Disentangle SSBD enumeration")
Signed-off-by: Waiman Long <longman@redhat.com>
