From e45af0e083dfc5d49dbad6965b9eeb3ac0072d82 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Mon, 14 May 2012 15:16:11 +0900 Subject: sh64: Kill off unused fixed I/O mapping window. This was reworked some time ago to go through fixmaps instead, leaving the range itself unused. As such, kill off the remaining references and hand over the remaining space for fixmaps directly. This also makes it possible to simplify the vmalloc fault case as we no longer have to care about the special section.
