This patch removes CONFIG_PMAC_PBOOK (PowerBook support). This is now split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some powerbooks have, CONFIG_PM for power management related code, and just left out of any CONFIG_* option for some generally useful stuff that can be used on non-laptops as well.
