This is a further cleanup of memalloc core stuff to do behave
more correctly regarding DMA API.  Formerly some x86-specific code
relied on the address from the page allocators, but rather we should
map correctly the pages with DMA mapping API.  With those fixes, the
fallback allocation should work more properly, so we can drop the
hackish check, too.
