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. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
