../arch/powerpc/kernel/traps.c:1663:6: error: no previous prototype for
‘stack_overflow_exception’ [-Werror=missing-prototypes]
void stack_overflow_exception(struct pt_regs *regs)
^~~~~~~~~~~~~~~~~~~~~~~~
A small sentence explaining how this is fixed would be welcome, so that
you don't need to read the code the know what the commit does to fix the
warning. Also the subject should be more explicit.

Note that asm-prototypes.h is not the right place for such a prototype,
but that's probably for another cleanup patch. See discussion at
