I'm not sure I understand the rationale for providing this help text if
this is def_bool depending on CONFIG_HUGETLB_PAGE.  Are you intending that
this is actually configurable and we want to provide guidance to the admin
on when to disable it (which it currently doesn't)?  If not, why have the
help text?

This is __not__ configurable. Seems like a comment to help others
understand this option. Like Randy said.

Yes, it could be written with '#' (or "comment") comment syntax instead of as help text.

Got it. I will update in the next version. Thanks.

I'm not sure that Kconfig is the right place to document functional 
behavior of the kernel, especially for non-configurable options.  Seems 
like this is already served by existing comments added by this patch 
series in the files where the description is helpful.
