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.

This option allows you to change some of the ways that
|
|
Linux manages its memory internally. Most users will
|
|
only have one option here: FLATMEM. This is normal
|
|
and a correct option.
|
|
|
|
If unsure, choose this option over any other.
