Merge tag 'kvm-x86-fixes-6.14-rcN' of https://github.com/kvm-x86/linux into HEAD
KVM fixes for 6.14 part 1
- Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being emulated
by KVM to fix a NULL pointer dereference.
- Enter guest mode (L2) from KVM's perspective before initializing the vCPU's
nested NPT MMU so that the MMU is properly tagged for L2, not L1.
- Load the guest's DR6 outside of the innermost .vcpu_run() loop, as the
guest's value may be stale if a VM-Exit is handled in the fastpath.
