With commit 4fe7ef3a (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. Signed-off-by:
