Subject: [PATCH 1/5] KVM: arm64: Hoist S2 PTE definitions into kvm_pgtable.h
Date: Wed, 11 Jan 2023 00:02:56 +0000	[thread overview]
Message-ID: <20230111000300.2034799-2-oliver.upton@linux.dev> (raw)
In-Reply-To: <20230111000300.2034799-1-oliver.upton@linux.dev>

KVM's definitions for S2 PTEs are scattered between kvm_pgtable.h and
pgtable.c. Keep it all in one place by moving it all into the header.

No functional change intended.
