Subject: [PATCH RESEND 09/30] KVM: x86: SVM: move avic definitions from AMD's spec to svm.h
Date: Mon,  7 Feb 2022 17:54:26 +0200	[thread overview]
Message-ID: <20220207155447.840194-10-mlevitsk@redhat.com> (raw)
In-Reply-To: <20220207155447.840194-1-mlevitsk@redhat.com>

asm/svm.h is the correct place for all values that are defined in
the SVM spec, and that includes AVIC.

Also add some values from the spec that were not defined before
and will be soon useful.
