MIPS: Add hibernation support
[Ralf: SMP support requires CPU hotplugging which MIPS currently doesn't support. As implemented in this patch cache and tlb flushing will also be invoked with interrupts disabled so smp_call_function() will blow up in charming ways. So limit to !SMP.] Reviewed-by: Pavel Machek <pavel@ucw.cz> Reviewed-by: Yan Hua <yanh@lemote.com> Reviewed-by: Arnaud Patard <apatard@mandriva.com> Reviewed-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Hu Hongbing <huhb@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
