arc, arm64, parisc and powerpc all have their own Kconfig symbols in place of the common CONFIG_PAGE_SIZE_4KB symbols. Change these so the common symbols are the ones that are actually used, while leaving the arhcitecture specific ones as the user visible place for configuring it, to avoid breaking user configs.
