It's not specific to this help text, but I start becoming a bit picky
about this issues:

If you understand this help text after reading it, you don't need a help
text for this option... ;-)

What is "NX support"?
What are "non-overcommit purposes"?
What is "pagetable lookup overhead"?

And if in doubt, should I say Y or N?

"System administrator who knows which hardware components he put into
the computer and which filesystems his data is on" might be a good
description for the average kconfig user, and these are the people who
should understand this help text.
