From: Ard Biesheuvel <ardb at kernel.org>

A couple of fixes and tweaks for KPTI - the first patch is a true
regression in v6.7, the others are minor tweaks.

v2:
- add two more tweaks
- use correct method to test system cap before alternatives have been
  applied
- move check into kpti_install_ng_mappings()
