4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ingo Molnar mingo@kernel.org
commit 1784f9144b143a1e8b19fe94083b040aa559182b upstream.
We'd like to use the 'PTI' acronym for 'Page Table Isolation' - free up the namespace by renaming the <linux/pti.h> driver header to <linux/intel-pti.h>.
(Also standardize the header guard name while at it.)
