Subject: [PATCH v17 18/20] KVM: arm64: Reuse kvm_stage2_unmap_range in kvm_unmap_gfn_range
Date: Tue, 8 Sep 2026 17:22:21 +0100 [thread overview]
Message-ID: <20260908162223.1683432-19-suzuki.poulose@arm.com> (raw)
In-Reply-To: <20260908162223.1683432-1-suzuki.poulose@arm.com>
In preparation for adding VM specific backends for stage2 operation,
switch to kvm_stage2_unmap_range() instead of __unmap_stage2_range()
from the kvm_unmap_gfn_range(). Drop the bail out check for protected
VMs and defer that to the one in kvm_stage2_unmap_range(). Later we
would replace the logic in kvm_stage2_unmap_range() with VM specific
backends.
No functional changes intended.
