Subject: [RFC] x86: cleanup of NX enabling

Hello all,

Posting this patch series for review; I intend to commit it to
tip:x86/mm unless someone objects over the next few days.

This came about based on Kees' original patch to give better dmesg
information about the status of NX availability.

Jeremy: I'm not 100% this is safe for Xen, as Xen takes its own path
for initialization, so if you could take a quick look, it would be
most appreciated.
