AP needs to be activated by spinning up an execution context for it.
The local apic emulation is now completely done in the hypervisor and it will
detect writes to the ICR_LO register that try to bring up the AP. In response
to such writes it will return to userspace with an exit code of SPINUP_AP.

the guest. Prior to the fix it was possible for such a bar to appear as a
32-bit bar as long as it was allocated from the region below 4GB.
This had the potential to confuse some drivers that were particular about
the size of the bars.

or 32-bit signed integer.
Simplify the handling of indirect addressing with displacement by
unconditionally adding the 'instruction->disp' to the target address.
This is alright since 'instruction->disp' is non-zero only for the
addressing modes that specify a displacement.

CR4. This bit is specific to the Intel VTX and removing it makes the library
more portable to AMD/SVM.
In the Intel VTX implementation, the hypervisor will ensure that this bit is
always set. See vmx_fix_cr4() for details.

zalloc and userboot seem to want to use ~600KB of heap space, which
results in a segfault when malloc fails in bhyveload.

These probes are most useful when looking into the structures
they provide, which are listed in io.d. For example:
dtrace -n 'io:genunix::start { printf("%d\n", args[0]->bio_bcount); }'
Note that the I/O systems in FreeBSD and Solaris/Illumos are sufficiently
different that there is not a 1:1 mapping from scripts that work
with one to the other.

PCI:
- Properly handle interrupt fallback from MSIX to MSI to legacy.
The host may not have sufficient resources to support MSIX,
so we must be able to fallback to legacy interrupts.
- Add interface to get the (sub) vendor and device IDs.
- Rename flags to VTPCI_FLAG_* like other VirtIO drivers.
Block:
- No longer allocate vtblk_requests from separate UMA zone.
malloc(9) from M_DEVBUF is sufficient. Assert segment counts
at allocation.
- More verbose error and debug messages.
Network:
- Remove stray write once variable.
Virtqueue:
- Shuffle code around in preparation of converting the mb()s to
the appropriate atomic(9) operations.
- Only walk the descriptor chain when freeing if INVARIANTS is
defined since the result is only KASSERT()ed.

If an error occurs when transmitting one mbuf in a chain of fragments,
free the subsequent fragments instead of leaking them.

the FIFO.
I still see some corner cases where no RX occurs when it should be
occuring. It's quite possible that there's a subtle race condition
somewhere; or maybe I'm not programming the RX queues right.
There's also no locking here yet, so any reset/configuration path
state change (ie, enabling/disabling receive from the ioctl, net80211
taskqueue, etc) could quite possibly confuse things.
