Subject: [PATCH 09/16] KVM: arm64: Hook up ->page_count() for hypervisor stage-1 page-table
Date: Wed, 13 Oct 2021 16:58:24 +0100	[thread overview]
Message-ID: <20211013155831.943476-10-qperret@google.com> (raw)
In-Reply-To: <20211013155831.943476-1-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.
