[PATCH 0/2] KPTI: get rid of cpu_entry_area mapping duplication

[Andy Lutomirski]

I like this variant much better.  It might also fix the nasty bug tglx
and peterz were chasing.

Andy Lutomirski (2):
  Undo the split of setup_cpu_entry_area
  x86/kpti: Reference all cpu_entry_area pagetables in the usermode
    tables
