Thanks; right now, I get this:

# modprobe -v kvm-intel
insmod /lib/modules/4.11.0-rc3+/kernel/virt/lib/irqbypass.ko 
insmod /lib/modules/4.11.0-rc3+/kernel/arch/x86/kvm/kvm.ko 
insmod /lib/modules/4.11.0-rc3+/kernel/arch/x86/kvm/kvm-intel.ko 
modprobe: ERROR: could not insert 'kvm_intel': Input/output error

but that appears to have nothing to do with the MWAIT patches. I'm
bisecting to find the root cause, but it's really slow...

I'll follow up when I know more... Thanks,
