+config MEMTEST_BOOTPARAM
+ bool "Memtest boot parameter"
+ depends on X86_64
+ default y
+ help
+ This option adds a kernel parameter 'memtest', which allows memtest
+ to be disabled at boot. If this option is selected, memtest
+ functionality can be disabled with memtest=0 on the kernel
+ command line. The purpose of this option is to allow a single
+ kernel image to be distributed with memtest built in, but not
+ necessarily enabled.
+
+ If you are unsure how to answer this question, answer Y.

+config MEMTEST_BOOTPARAM_VALUE
+ int "Memtest boot parameter default value (0-4)"
+ depends on MEMTEST_BOOTPARAM
+ range 0 4
+ default 0
+ help
+ This option sets the default value for the kernel parameter
+ 'memtest', which allows memtest to be disabled at boot. If this
+ option is set to 0 (zero), the memtest kernel parameter will
+ default to 0, disabling memtest at bootup. If this option is
+ set to 4, the memtest kernel parameter will default to 4,
+ enabling memtest at bootup, and use that as pattern number.
+
+ If you are unsure how to answer this question, answer 0.
