Merge tag 'kvm-x86-misc-6.16' of https://github.com/kvm-x86/linux into HEAD
KVM x86 misc changes for 6.16:
- Unify virtualization of IBRS on nested VM-Exit, and cross-vCPU IBPB, between
SVM and VMX.
- Advertise support to userspace for WRMSRNS and PREFETCHI.
- Rescan I/O APIC routes after handling EOI that needed to be intercepted due
to the old/previous routing, but not the new/current routing.
- Add a module param to control and enumerate support for device posted
interrupts.
- Misc cleanups.
