Subject: [PATCH 06/11] KVM: SVM: remove dead field from struct svm_cpu_data
Date: Wed,  9 Nov 2022 09:51:51 -0500	[thread overview]
Message-ID: <20221109145156.84714-7-pbonzini@redhat.com> (raw)
In-Reply-To: <20221109145156.84714-1-pbonzini@redhat.com>

The "cpu" field of struct svm_cpu_data has been write-only since commit
4b656b120249 ("KVM: SVM: force new asid on vcpu migration", 2009-08-05).
Remove it.
