From adac9570966eb2eb137209e552b258d4d1d4825b Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 28 Dec 2006 10:54:01 +0900 Subject: [PATCH] sh: Don't set reserved _PAGE_WT bit on SH-3. Only SH-4 needs to set _PAGE_WT when using write-through caching, don't attempt to set it on SH-3 where it ends up being a reserved bit.
