Merge commit 'a849088aa1' from rmk/fixes into cleanup/io-pci
As Stephen Rothwell reports, a849088aa155 ("ARM: Fix ioremap() of address zero") from the arm-current tree and commit c2794437091a ("ARM: Add fixed PCI i/o mapping") from the arm-soc tree conflict in a nontrivial way in arch/arm/mm/mmu.c. Rob Herring explains: The PCI i/o reserved area has a dummy physical address of 0 and needs to be skipped by ioremap searches. So we don't set VM_ARM_STATIC_MAPPING to prevent matches by ioremap. The vm_struct settings don't really matter when we do the real mapping of the i/o space. Since commit a849088aa155 is at the start of the fixes branch in the arm tree, we can merge it into the branch that contains the other ioremap changes.
