Subject: mn10300: Declare __pfn_to_phys() to fix build error
__pfn_to_phys() was introduced with commit 8b79eb6f5b53e ("libnvdimm, pfn,
pmem: allocate memmap array in persistent memory") but not declared for
mn10300. This results in the following build error.
mm/page_alloc.c: In function 'memmap_init_zone':
mm/page_alloc.c:4610:9: error: implicit declaration of function '__pfn_to_phys'
Fixes: 8b79eb6f5b53e ("libnvdimm, pfn, pmem: allocate memmap array in persistent memory")
