Well, if we're pointing to a CDN then really there is no longer any
reason to point users to www.XXX.kernel.org with XX = country code,
since that's what a CDN is doing automatically.

Yes, of course. But I still think the wording is wrong. The wording
feels like something for the commit log, not for the help text. A
correct wording for the help text could be:

	The default value points to kernel.org's CDN, which will
	automatically redirect you to a mirror geographically close to
	you.

Right.
