map_physmem should return a pointer that can be used by the CPU to access the given memory - on MIPS simply returning the physical address as it does prior to this patch doesn't achieve that. Instead return a pointer to the memory within (c)kseg0, which matches up consistently with the (c)kseg1 pointer that uncached mappings return via ioremap.
