Subject: [PATCH 5/7] um: Remove custom definition of mk_pte()
Date: Mon, 17 Feb 2025 19:08:32 +0000 [thread overview]
Message-ID: <20250217190836.435039-6-willy@infradead.org> (raw)
In-Reply-To: <20250217190836.435039-1-willy@infradead.org>
Move the pfn_pte() definitions from the 2level and 4level files to the
generic pgtable.h and delete the custom definition of mk_pte() so that
we use the central definition.
