Subject[PATCH v4 04/14] KVM: arm64: Hook up ->page_count() for hypervisor stage-1 page-table
From
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.
