Subject: [PATCH v1 01/11] arm/pgtable: define PFN_PTE_SHIFT on arm and arm64
Date: Mon, 22 Jan 2024 20:41:50 +0100
Message-ID: <20240122194200.381241-2-david@redhat.com>
In-Reply-To: <20240122194200.381241-1-david@redhat.com>

We want to make use of pte_next_pfn() outside of set_ptes(). Let's
simpliy define PFN_PTE_SHIFT, required by pte_next_pfn().
