mm: move ioremap_page_range to vmalloc.c

Browse Source 
Patch series "small ioremap cleanups".

The first patch moves a little code around the vmalloc/ioremap boundary
following a bigger move by Nick earlier.  The second enforces
non-executable mapping on ioremap just like we do for vmap.  No driver
currently uses executable mappings anyway, as they should.

This patch (of 2):

This keeps it together with the implementation, and to remove the
vmap_range wrapper.
