[PATCH][MTD] mtdpart.c: allow other drivers to get physical address of partition

Hey I just thought of a different approach.  What about something like:

int mtd_insert_mem(struct mtd_info *mtd, struct vm_area_struct *vma,
unsigned long addr, unsigned long offset)
{
     struct map_info *map = mtd->priv;
     unsigned long pfn;

     pfn = (map->phys + offset) >> PAGE_SHIFT;
     return vm_insert_pfn(vma, addr, pfn);
}



This way we don't need to export the physical address and we keep the
vm calls in the driver world.
