Philippe DeMuyter noticed this build failure with Linus' current git

pass it directly to Linus.

Sorry, I saw his patch before, but had no spare cycles left for testing.

Unfortunately that breaks CONFIG_MMU=y:

arch/m68k/include/asm/irqflags.h: In function âarch_local_irq_enableâ:
arch/m68k/include/asm/irqflags.h:43: error: implicit declaration of
function âhardirq_countâ

But if you protect the #include<linux/hardirq.h> by #ifdef
CONFIG_MMU, I'm happy with
it.

Thanks, I'll rework it with that.

Regards
Greg
