Subject: [PATCH 5/9] KVM: arm64: Add kvm_uninit_stage2_mmu()
Date: Fri, 13 Jan 2023 03:49:56 +0000	[thread overview]
Message-ID: <20230113035000.480021-6-ricarkol@google.com> (raw)
In-Reply-To: <20230113035000.480021-1-ricarkol@google.com>

Add kvm_uninit_stage2_mmu() and move kvm_free_stage2_pgd() into it. A
future commit will add some more things to do inside of
kvm_uninit_stage2_mmu().

No functional change intended.
