v4.12-rc0: NR_DEV_DAX has no help

[Pavel Machek]

Hi!

I got CONFIG_DAX forced on my (not sure why, not sure what it is), and
so it wants to know   Maximum number of Device-DAX instances
(NR_DEV_DAX) [32768] (NEW).

Unfortunately, it has no help text.

I'm not sure what DAX is good for, and certainly don't know what is
right value to set there...
