From 9460c0ce9b29825d279081d5078815a32c268ada Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 21 Mar 2008 18:08:58 +0900 Subject: [PATCH] sh: Fix up __access_ok() check for nommu. Presently this only checks to see if an address is an RAM, but this doesn't work with XIP, so just always return 1. Follows m68knommu.
