Subject: [PATCH v1 05/11] s390/pgtable: define PFN_PTE_SHIFT
Date: Mon, 22 Jan 2024 20:41:54 +0100 [thread overview]
Message-ID: <20240122194200.381241-6-david@redhat.com> (raw)
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().
