remove all PG_G global page mappings from the kernel when running on
Intel CPUs. Part of an ongoing set of commits to mitigate the Intel
"meltdown" CVE. This diff does not confer any immunity to that
vulnerability - subsequent commits are still needed and are being
worked on presently.

ok guenther, deraadt
