- use the new virtual APIC page - update to current bhyve APIs Tested by Anish with multiple FreeBSD SMP VMs on a Phenom, and verified by myself with light FreeBSD VM testing on a Sempron 3850 APU. The issues reported with Linux guests are very likely to still be here, but this sync eliminates the skew between the project branch and CURRENT, and should help to determine the causes. Some follow-on commits will fix minor cosmetic issues. Submitted by: Anish Gupta (akgupt3@gmail.com)
