Merge branch 'kvm-x86-mmu-6.6' into HEAD
KVM x86 MMU changes for 6.6:
- Rip out the ancient MMU_DEBUG crud and replace the useful bits with
CONFIG_KVM_PROVE_MMU
- Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the API surface
that is needed by external users (currently only KVMGT), and fix a variety
of issues in the process
- Fix KVM's handling of !visible guest roots to avoid premature triple fault
injection by loading a dummy root backed by the zero page
