Description

Hi,

I get this panic on master.
http://leaf.dragonflybsd.org/~mh/vmzeroidle.jpg
Kernel: DragonFly v2.7.3.793.gcbfc8-DEVELOPMENT (aug 30)

If I set vm.idlezero_enable=0 in /boot/loader.conf it boots successfully.

I believe that the issue was that I was enabling bzeront() { which uses the
movnti instruction } at SSE, not SSE2. I've just committed a patch to fix this;
would love to hear if it does.
