[PATCH 2/3] mm/Kconfig: hide "Memory Model" selection menu

[PATCH 2/3] mm/Kconfig: hide "Memory Model" selection menu

[Dave Hansen]

I got some feedback from users who think that the new "Memory
Model" menu is a little invasive.  This patch will hide that menu,
except when CONFIG_EXPERIMENTAL is enabled *or* when an individual
architecture wants it.

An individual arch may want to enable it because they've removed
their arch-specific DISCONTIG prompt in favor of the mm/Kconfig one.
