acquiring the tty lock in bvm_tty_close(). Instead just assert that the tty
lock is held before calling callout_reset().

- Set the console name always so that the bvm console device can be used
via conscontrol even if it isn't chosen as the default console.

run as a 1/2 CPU guest on an 8.1 bhyve host.
bhyve/inout.c
inout.h
fbsdrun.c
- Rather than exiting on accesses to unhandled i/o ports, emulate
hardware by returning -1 on reads and ignoring writes to unhandled
ports. Support the previous mode by allowing a 'strict' parameter
to be set from the command line.
The 8.1 guest kernel was vastly cut down from GENERIC and had no
ISA devices. Booting GENERIC exposes a massive amount of random
touching of i/o ports (hello syscons/vga/atkbdc).
bhyve/consport.c
dev/bvm/bvm_console.c
- implement a simplistic signature for the bvm console by returning
'bv' for an inw on the port. Also, set the priority of the console
to CN_REMOTE if the signature was returned. This works better in
an environment where multiple consoles are in the kernel (hello syscons)
bhyve/rtc.c
- return 0 for the access to RTC_EQUIPMENT (yes, you syscons)
amd64/vmm/x86.c
x86.h
- hide a bunch more CPUID leaf 1 bits from the guest to prevent
cpufreq drivers from probing.
The next step will be to move CPUID handling completely into
user-space. This will allow the full spectrum of changes from
presenting a lowest-common-denominator CPU type/feature set, to
exposing (almost) everything that the host can support.

This branch is now considered frozen: future bhyve development will take
place in a branch off -CURRENT.
sys/dev/bvm/bvm_console.c
sys/dev/bvm/bvm_dbg.c
- simple console driver/gdb debug port used for bringup. supported
by user-space bhyve executable
sys/conf/options.amd64
sys/amd64/amd64/minidump_machdep.c
- allow NKPT to be set in the kernel config file
sys/amd64/conf/GENERIC
- mptable config options; bhyve user-space executable creates an mptable
with number of CPUs, and optional vendor extension
- add bvm console/debug
- set NKPT to 512 to allow loading of large RAM disks from the loader
- include kdb/gdb
sys/amd64/amd64/local_apic.c
sys/amd64/amd64/apic_vector.S
sys/amd64/include/specialreg.h
- if x2apic mode available, use MSRs to access the local APIC, otherwise
fall back to 'classic' MMIO mode
sys/amd64/amd64/mp_machdep.c
- support AP spinup on CPU models that don't have real-mode support by
overwriting the real-mode page with a message that supplies the bhyve
user-space executable with enough information to start the AP directly
in 64-bit mode.
sys/amd64/amd64/vm_machdep.c
- insert pause statements into cpu shutdown busy-wait loops
sys/dev/blackhole/blackhole.c
sys/modules/blackhole/Makefile
- boot-time loadable module that claims all PCI bus/slot/funcs specified
in an env var that are to be used for PCI passthrough
sys/amd64/amd64/intr_machdep.c
- allow round-robin assignment of device interrupts to CPUs to be disabled
from the loader
sys/amd64/include/bus.h
- convert string ins/outs instructions to loops of individual in/out since
bhyve doesn't support these yet
sys/kern/subr_bus.c
- if the device was no created with a fixed devclass, then remove it's
association with the devclass it was associated with during probe.
Otherwise, new drivers do not get a chance to probe/attach since the
device will stay married to the first driver that it probed successfully
but failed to attach.
