I agree.

Today we have:

arch/hexagon/Kconfig:config PAGE_SIZE_4KB
arch/hexagon/Kconfig:config PAGE_SIZE_16KB
arch/hexagon/Kconfig:config PAGE_SIZE_64KB
arch/hexagon/Kconfig:config PAGE_SIZE_256KB
arch/mips/Kconfig:config PAGE_SIZE_4KB
arch/mips/Kconfig:config PAGE_SIZE_8KB
arch/mips/Kconfig:config PAGE_SIZE_16KB
arch/mips/Kconfig:config PAGE_SIZE_32KB
arch/mips/Kconfig:config PAGE_SIZE_64KB
arch/sh/mm/Kconfig:config PAGE_SIZE_4KB
arch/sh/mm/Kconfig:config PAGE_SIZE_8KB
arch/sh/mm/Kconfig:config PAGE_SIZE_16KB
arch/sh/mm/Kconfig:config PAGE_SIZE_64KB


I think we should convert all other architectures to that syntax.
