In linux kernel since version 2.6.21 (release Date: 2007-04-25)
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.
