The following commit has been merged into the x86/cpu branch of tip: Commit-ID: b39033f504a7eda15dcb2465679b8d46651b3645 Gitweb: https://git.kernel.org/tip/b39033f504a7eda15dcb2465679b8d46651b3645 Author: Sean Christopherson <sean.j.christopherson@xxxxxxxxx> AuthorDate: Fri, 20 Dec 2019 20:45:11 -08:00 Committer: Borislav Petkov <bp@xxxxxxx> CommitterDate: Mon, 13 Jan 2020 19:29:16 +01:00 KVM: VMX: Use VMX_FEATURE_* flags to define VMCS control bits Define the VMCS execution control flags (consumed by KVM) using their associated VMX_FEATURE_* to provide a strong hint that new VMX features are expected to be added to VMX_FEATURE and considered for reporting via /proc/cpuinfo. No functional change intended.
