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.

Recent changes to header files made kernel compilation for m68k/m68knommu

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
