[GIT PULL] KVM: x86 pull requests 6.18

[Sean Christopherson]

Sorry this is coming in late, it's been a long week.

Similar to 6.17, a few anomolies in the form of external and cross-branch
dependencies, but thankfully only one conflict that I know of (details in
CET pull request).  Oh, and one "big" anomoly: there's a pull request for
guest-side x86/kvm changes (but it's small, hence the quotes).

I tried my best to document anything unusual in the individual pull requests,
so hopefully nothing is too surprising.
