Subject: [PATCH v3 18/21] KVM: arm64: Check the pgt instead of the pgd when modifying page-table

From: Will Deacon <[email-masked]>
Date: Tue, 25 Aug 2020 10:39:50 +0100

In preparation for removing the 'pgd' field of 'struct kvm_s2_mmu',
update the few remaining users to check the 'pgt' field instead.
