s390: move dummy io_remap_pfn_range() to asm/pgtable.h
commit 4f2e29031e6c67802e7370292dd050fd62f337ee upstream. Commit b4cbb197c7e7 ("vm: add vm_iomap_memory() helper function") added a helper function wrapper around io_remap_pfn_range(), and every other architecture defined it in <asm/pgtable.h>. The s390 choice of <asm/io.h> may make sense, but is not very convenient for this case, and gratuitous differences like that cause unexpected errors like this: mm/memory.c: In function 'vm_iomap_memory': mm/memory.c:2439:2: error: implicit declaration of function 'io_remap_pfn_range' [-Werror=implicit-function-declaration] Glory be the kbuild test robot who noticed this, bisected it, and reported it to the guilty parties (ie me).
