MIPS: add support for 64 bit addressing
Prepare for upcoming mips64 support. This patch add mips64 address support. Signed-off-by: Zhizhou Zhang <etou.zh@gmail.com> [daniel.schwierzeck@gmail.com: prefer _MIPS_SZLONG in posix_types.h to fix some warnings] Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
