Subject: [PATCH v3 05/15] KVM: arm64: Hook up ->page_count() for hypervisor stage-1 page-table
Date: Wed, 1 Dec 2021 17:03:59 +0000 [thread overview]
Message-ID: <20211201170411.1561936-6-qperret@google.com> (raw)
In-Reply-To: <20211201170411.1561936-1-qperret@google.com>
From: Will Deacon <will@kernel.org>
kvm_pgtable_hyp_unmap() relies on the ->page_count() function callback
being provided by the memory-management operations for the page-table.
Wire up this callback for the hypervisor stage-1 page-table.
