2009-03-16sh: SuperH Mobile suspend supportMagnus Damm
This patch contains CONFIG_SUSPEND support to the SuperH architecture. If enabled, SuperH Mobile processors will register their suspend callbacks during boot. To suspend, use "echo mem > /sys/power/state". To allow wakeup, make sure "/sys/device/platform/../power/wakeup" contains "enabled". Additional per-device driver patches are most likely needed.

2009-03-10sh: hibernation supportMagnus Damm
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.

2009-02-27sh: multiple vectors per irq - baseMagnus Damm
Instead of keeping the single vector -> single linux irq mapping we extend the intc code to support merging of vectors to a single linux irq. This helps processors such as sh7750, sh7780 and sh7785 which have more vectors than masking ability. With this patch in place we can modify the intc tables to use one irq per maskable irq source. Please note the following: - If multiple vectors share the same enum then only the first vector will be available as a linux irq. - Drivers may need to be rewritten to get pending irq source from the hardware block instead of irq number. This patch together with the sh7785 specific intc tables solves DMA controller irq issues related to buggy interrupt masking.
