I'm not sure why I'm trying here any more. You do seem quite content to
add as much cruft to ppc and every other architecture as possible. If
your theoretical scenario pops up, you simply do this in ppc:
config ARCH_FAULT_AROUND_ORDER
int
default 999
default 888 if OTHER_SILLY_POWERPC_SUBARCH
But *ONLY* in the architectures that care about doing that stuff. You
leave every other architecture on the planet alone. Then, in mm/Kconfig:
config FAULT_AROUND_ORDER
int
default ARCH_FAULT_AROUND_ORDER if ARCH_FAULT_AROUND_ORDER
default 4
Your way still requires going and individually touching every single
architecture's Kconfig that wants to enable fault around. That's not an
acceptable solution.
