These are still good (IMO).

Oops. Just see I was too fast. After reading it again I see that the y/n 
value is correct after all.

However, it also means that the new description is probably too short.
The phrase "allows memtest to be set" does not really mean anything to a 
user who does not know what memtest really does. It also does not explain 
that memtest is a boot parameter.

Also, it should probably be made more explicit that no memtest is actually 
performed unless the memtest boot parameter is passed at the boot prompt.

Looks like 4 is the maximum possible value. This should be mentioned 
explicitly (here as well as in Documentation/kernel-parameters.txt).

Maybe something like this:
	This option allows a memory test to be executed when the system is
	booted. A memory test is only actually executed if the kernel boot
	parameter 'memtest' is passed.

	The value of that parameter is the number to times the test is
	performed:
		memtest=0: don't perform the test (default)
		memtest=1: perform the test once
		...
		memtest=4: perform the test 4 times (maximum).

	If you are unsure how to answer this question, answer Y.

Hmmm. The original description mentions "N patterns". If those patterns are 
actually different, then a different description is probably needed.

Sorry for the confusion.

FJP
