My guess is "unaware". Most folks aren't even aware of
the problem hugepages address. That sort of knowledge is
frowned upon by the point-and-click tuition brigade,
nowadays.
And in some cases it's taken care of silently, which
is IMO the best way to approach this. Make it part
of default settings if the h/w addressing is 64-bit
class: that way no one can forget to "click" it on.
