- bool "Switch kernel/user addressing modes"
- help
- This option allows to switch the addressing modes of kernel and user
- space. The kernel parameter switch_amode=on will enable this feature,
- default is disabled. Enabling this (via kernel parameter) on machines
- earlier than IBM System z9-109 EC/BC will reduce system performance.

- Note that this option will also be selected by selecting the execute
- protection option below. Enabling the execute protection via the
- noexec kernel parameter will also switch the addressing modes,
- independent of the switch_amode kernel parameter.
