Subject: [PATCH 0/5] x86, mm: PTI Global page fixes for 4.17

There have been a number of reports about issues with the patches that
restore the Global PTE bit when using KPIT.  This set resolves all of
the issues that have been reported.

These have been pushed out to a git tree where 0day should be chewing
on them.  Considering the troubles thus far, we should probably wait
for 0day to spend _some_ time on these fixes before these get merged.
