From a41d3862dfd44a1b09a0f6243bb34773061fd9a2 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Thu, 23 Mar 2006 01:07:00 -0700 Subject: [PARISC] Remove obsolete CONFIG_DEBUG_IOREMAP Remove CONFIG_DEBUG_IOREMAP, it's now obsolete and won't work anyway. Remove it from lib/KConfig since it was only available on parisc.
