Linas Vepstas d177c207ba [PATCH] powerpc: IOMMU: don't ioremap null addresses 
240-ioremap-null-ptr-test.patch

Under highly unusual circumstances, a buggy driver will ask a null ptr
to be ioremapped, an operation that curently succeeds but leads to
later trouble.  Instead, refuse to remap the null pointer.
