Subject: [PATCH v3 03/36] KVM: arm64: Rename __pkvm_pgtable_stage2_unmap()

From: Will Deacon <[email-masked]>
Date: Thu, 5 Mar 2026 14:43:16 +0000

In preparation for adding support for protected VMs, where pages are
donated rather than shared, rename __pkvm_pgtable_stage2_unmap() to
__pkvm_pgtable_stage2_unshare() to make it clearer about what is going
on.
