Hi Christoph,

Compile testing revealed:

   LD      vmlinux
kernel/built-in.o: In function `ack_bad':
handle.c:(.text+0x215f6): undefined reference to `ack_bad_irq'
kernel/built-in.o: In function `handle_bad_irq':
(.text+0x219dc): undefined reference to `ack_bad_irq'
make[2]: *** [vmlinux] Error 1


I did this to fix it:

--- a/arch/m68k/include/asm/hardirq_no.h
+++ b/arch/m68k/include/asm/hardirq_no.h
@@ -14,9 +14,6 @@
  # error HARDIRQ_BITS is too low!
  #endif

-void ack_bad_irq(unsigned int irq);
-#define ack_bad_irq ack_bad_irq
-
  #include <asm-generic/hardirq.h>

  #endif /* __M68K_HARDIRQ_H */

What do you think?

Regards
Greg
