Subject: [PATCH v2 03/11] sparc32: Remove custom definition of mk_pte()
Date: Wed,  2 Apr 2025 19:16:57 +0100	[thread overview]
Message-ID: <20250402181709.2386022-4-willy@infradead.org> (raw)
In-Reply-To: <20250402181709.2386022-1-willy@infradead.org>

Instead of defining pfn_pte() in terms of mk_pte(), make pfn_pte() the
base implementation.  That lets us use the generic definition of mk_pte().
