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.

+ to be set.
+ memtest=0, mean disabled; -- default
+ memtest=1, mean do 1 test pattern;

+ memtest=4, mean do 4 test patterns.
If you are unsure how to answer this question, answer Y.

- 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.
