341f19c949 Get rid of assumptions in the hypervisor that the host physical memory 
associated with guest physical memory is contiguous.

In this case vm_malloc() was using vm_gpa2hpa() to indirectly infer whether
or not the address range had already been allocated.

Replace this instead with an explicit API 'vm_gpa_available()' that returns
TRUE if a page is available for allocation in guest physical address space.

e90273829b Add ioctls to control the X2APIC capability exposed by the virtual machine to 
the guest.

At the moment this simply sets the state in the 'vcpu' instance but there is
no code that acts upon these settings.

cd942e0f25 MSI-x interrupt support for PCI pass-thru devices. 
Includes instruction emulation for memory r/w access. This
opens the door for io-apic, local apic, hpet timer, and
legacy device emulation.

366f60834f Import of bhyve hypervisor and utilities, part 1. 
vmm.ko - kernel module for VT-x, VT-d and hypervisor control
  bhyve  - user-space sequencer and i/o emulation
  vmmctl - dump of hypervisor register state
  libvmm - front-end to vmm.ko chardev interface

bhyve was designed and implemented by Neel Natu.
