Subject: [PATCH v4 04/14] KVM: arm64: Hook up ->page_count() for hypervisor stage-1 page-table
Date: Wed, 15 Dec 2021 16:12:21 +0000 [thread overview]
Message-ID: <20211215161232.1480836-5-qperret@google.com> (raw)
In-Reply-To: <20211215161232.1480836-1-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.
