Add Suspend-to-disk / swsusp / CONFIG_HIBERNATION support to the SuperH architecture. To suspend, use "swapon /dev/sda2; echo disk > /sys/power/state" To resume, pass "resume=/dev/sda2" on the kernel command line. The patch "pm: rework includes, remove arch ifdefs V2" is needed to allow the generic swsusp code to build properly. Hibernation is not enabled with this patch though, a patch setting ARCH_HIBERNATION_POSSIBLE will be submitted later.
