From 8415a74852d7c24795007ee9862d25feb519007c Mon Sep 17 00:00:00 2001 From: Kim Phillips <kim.phillips@amd.com> Date: Tue, 10 Jan 2023 16:46:37 -0600 Subject: x86/cpu, kvm: Add support for CPUID_80000021_EAX Add support for CPUID leaf 80000021, EAX. The majority of the features will be used in the kernel and thus a separate leaf is appropriate. Include KVM's reverse_cpuid entry because features are used by VM guests, too.
