From 8a2b6255dd11eee1b27d1be394241abf1871b610 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Sat, 10 Mar 2012 21:24:04 -0600 Subject: [PATCH] ARM: fix ioremap/iounmap for !CONFIG_MMU With commit 4fe7ef3a081 (ARM: provide runtime hook for ioremap/iounmap), compiles with !CONFIG_MMU were broken. Rename nommu __iounmap to __arm_iounmap and add arch_ioremap_caller and arch_iounmap. Its not expected that these need to be overriden for !CONFIG_MMU, so setting the function ptrs has no effect in this case.
