[SPARC64]: Privatize sun4u_get_pte() and fix name.
__get_phys is only called from init.c as is prom_virt_to_phys(), __get_iospace() is not called at all, and sun4u_get_pte() is largely misnamed. Privatize the implementation and helper functions of sun4u_get_phys() to mm/init.c, and rename to kvaddr_to_paddr(). The only used of this thing is flush_icache_range(), and thus things can be considerably further simplified. For example, we should only see module or PAGE_OFFSET kernel addresses here, so we don't need the OBP firmware range handling at all. Signed-off-by: David S. Miller <davem@davemloft.net>
