Sorry, I can not figure out what you want.
As far as I look the source tree,arch/ppc/kernel/setup.c does not have 
the function called early_param.
Would you give me a more precise explanation?

Certainly, moving the interrupt handler from 
drivers/char/watchdog/booke_wdt.c to arch/ppc/kernel/traps.c
is easy, but I can not tell whether it is good or not.

But the handler is not used by the core kernel.
 From this point of view, the handler should not be placed
in arch/ppc/kernel/traps.c. This is the reason why I locate
the exception handler in the driver part.

Anyway, I'll try to move this handler into arch/ppc/kernel/traps.c
for the moment.
