Ingo Molnar c08d517480 Revert "x86/PAT: Fix Xorg regression on CPUs that don't support PAT" ...

This reverts commit cbed27cdf0.

As Andy Lutomirski observed:

 "I think this patch is bogus. pat_enabled() sure looks like it's
  supposed to return true if PAT is *enabled*, and these days PAT is
  'enabled' even if there's no HW PAT support."
