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.
