Found few other similar arch users. See attached patch. ioremap_page() in arch/arm/mm/ioremap.c is an interesting case. It is EXPORT_SYMBOL, but there are no in-tree users. I think we shouldn't apply checks to it, since some out-of-tree module may fail. I have no arm boards to test, I suggest we play safe than sorry.
