Subject: [PATCH RFC v1 8/9] KVM: Move kvm_for_each_memslot_in_hva_range() to be used in SVM
Date: Tue, 8 Mar 2022 10:08:56 +0530 [thread overview]
Message-ID: <20220308043857.13652-9-nikunj@amd.com> (raw)
In-Reply-To: <20220308043857.13652-1-nikunj@amd.com>
Move the macro to kvm_host.h and make if visible for SVM to use.
No functional change intended.
