config S390_SWITCH_AMODE

	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.





config S390_EXEC_PROTECT

	bool "Data execute protection"

	select S390_SWITCH_AMODE

	help

	  This option allows to enable a buffer overflow protection for user

	  space programs and it also selects the addressing mode option above.
