MIPS: Fix modpost error in modules attepting to use virt_addr_valid().
ERROR: "min_low_pfn" [drivers/block/aoe/aoe.ko] undefined! Fixed by moving the implementation of virt_addr_valid() into the kernel proper and exporting it which removes the pains of an inline or macro implementation. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
