*(No prompt -- not directly user assignable.)*

Type: ``bool``

Help
====

This hidden option is selected by the target architecture if
architecture-specific data is needed on a per memory domain basis.
If so, the architecture defines a 'struct arch_mem_domain' which is
embedded within every struct k_mem_domain. The architecture
must also define the arch_mem_domain_init() function to set this up
when a memory domain is created.

Typical uses might be a set of page tables for that memory domain.

Direct dependencies
===================

\ :option:`USERSPACE <CONFIG_USERSPACE>`

*(Includes any dependencies from ifs and menus.)*

Defaults
========

No defaults. Implicitly defaults to ``n``.
