Subject: [PATCH 15/24] KVM: nSVM: remove HF_HIF_MASK
Date: Wed, 20 May 2020 13:21:36 -0400	[thread overview]
Message-ID: <20200520172145.23284-16-pbonzini@redhat.com> (raw)
In-Reply-To: <20200520172145.23284-1-pbonzini@redhat.com>

The L1 flags can be found in the save area of svm->nested.hsave, fish
it from there so that there is one fewer thing to migrate.
