#     powerpc/mm: refactor ioremap_range() and use ioremap_page_range()
#     
#     book3s64's ioremap_range() is almost same as fallback ioremap_range(),
#     except that it calls radix__ioremap_range() when radix is enabled.
#     
#     radix__ioremap_range() is also very similar to the other ones, expect
#     that it calls ioremap_page_range when slab is available.
#     
#     Lets keep only one version of ioremap_range() which calls
#     ioremap_page_range() on all platforms when slab is available.
#     
#     At the same time, drop the nid parameter which is not used.
