Hi Rich,

After merging the sh tree, today's linux-next build (powerpc allyesconfig)
failed like this:

drivers/clocksource/jcore-pit.c:145:20: error: conflicting types for 'timer_interrupt'
 static irqreturn_t timer_interrupt(int irq, void *dev_id)
                    ^
In file included from arch/powerpc/include/asm/irqflags.h:11:0,
                 from include/linux/irqflags.h:15,
                 from include/linux/spinlock.h:53,
                 from include/linux/mmzone.h:7,
                 from include/linux/gfp.h:5,
                 from include/linux/slab.h:14,
                 from drivers/clocksource/jcore-pit.c:12:
arch/powerpc/include/asm/hw_irq.h:36:13: note: previous declaration of 'timer_interrupt' was here
 extern void timer_interrupt(struct pt_regs *);
             ^

Caused by commit

  e0aa0655c60b ("clocksource: add J-Core timer/clocksource driver")

I added this fix patch:
