Good point. This seems to trigger much deeper changes. All of these
and their logic go away:

arch/arm/Kconfig:config ARCH_SELECT_MEMORY_MODEL
arch/arm/mach-clps711x/Kconfig: select ARCH_SELECT_MEMORY_MODEL
arch/arm64/Kconfig:config ARCH_SELECT_MEMORY_MODEL
arch/ia64/Kconfig:config ARCH_SELECT_MEMORY_MODEL
arch/parisc/Kconfig:config ARCH_SELECT_MEMORY_MODEL
arch/powerpc/Kconfig:config ARCH_SELECT_MEMORY_MODEL
arch/s390/Kconfig:config ARCH_SELECT_MEMORY_MODEL
arch/sh/mm/Kconfig:config ARCH_SELECT_MEMORY_MODEL
arch/sparc/Kconfig:config ARCH_SELECT_MEMORY_MODEL
arch/x86/Kconfig:config ARCH_SELECT_MEMORY_MODEL

Along with mm/Kconfig:config SELECT_MEMORY_MODEL and associated logic.

How about we handle this as a phase 2, and for phase 1, I just drop
EXPERIMENTAL?
