Subject: [PATCH v2 03/15] nios2/pgtable: define PFN_PTE_SHIFT
Date: Thu, 25 Jan 2024 20:32:15 +0100 [thread overview]
Message-ID: <20240125193227.444072-4-david@redhat.com> (raw)
In-Reply-To: <20240125193227.444072-1-david@redhat.com>
We want to make use of pte_next_pfn() outside of set_ptes(). Let's
simply define PFN_PTE_SHIFT, required by pte_next_pfn().
