From 6c70b6fc7b6fc321636a014082d9e32333da1f80 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 8 Aug 2007 17:11:39 -0700 Subject: [SPARC64]: Do not assume sun4v chips have load-twin/store-init support. Check the cpu type in the OBP device tree before committing to using the optimized Niagara memcpy and memset implementation. If we don't recognize the cpu type, use a completely generic version.
