Prior to this change a page fault would be detected in vm_copyout(). This
was done after the I/O port access was done. If the I/O port access had
side-effects (e.g. reading the uart FIFO) then restarting the instruction
would result in incorrect behavior.
Fix this by validating the guest linear address before doing the I/O port
emulation. If the validation results in a page fault exception being injected
into the guest then the instruction can now be restarted without any
side-effects.

While the current implementation is simplistic it forms the basis of doing

The emulation is constrained in a number of ways: 64-bit only, doesn't check

registers at 0x60-63 and 0x68-6b.
- For each configured PCI INTx interrupt, route it to both an I/O APIC
pin and a PCI interrupt router pin. When a PCI INTx interrupt is
asserted, ensure that both pins are asserted.
- Provide an initial routing of PCI interrupt router (PIRQ) pins to
8259A pins (ISA IRQs) and initialize the interrupt line config register
for the corresponding PCI function with the ISA IRQ as this matches
existing hardware.
- Add a global _PIC method for OSPM to select the desired interrupt routing
configuration.
- Update the _PRT methods for PCI bridges to provide both APIC and legacy
PRT tables and return the appropriate table based on the configured
routing configuration. Note that if the lpc device is not configured, no
routing information is provided.
- When the lpc device is enabled, provide ACPI PCI link devices corresponding
to each PIRQ pin.

converted into the SPINDOWN_CPU exitcode . The bhyve(8) process would exit
the vcpu thread in response to a SPINDOWN_CPU and when the last vcpu was
spun down it would reset the virtual machine via vm_suspend(VM_SUSPEND_RESET).
This functionality was broken in r263780 in a way that made it impossible
to kill the bhyve(8) process because it would loop forever in
vm_handle_suspend().
Unbreak this by removing the code to spindown vcpus. Thus a 'halt' from

different things from this commit:
+ More devices. Devices that were previously ignored are now present.
+ Faster device scanning. "There is no try, only Do" -- f_device_try()
is no longer the basis of device scanning as GEOM provides [nearly]
all devices (doesn't provide network devices).
+ More information available as non-root. Usually you have to be root
to do things like taste filesystems, and that limits the amount of
information available to non-root users; with GEOM, we see all even
running unprivileged as the brunt of information (except for so-
called ``dangerously dedicated'' file systems) is represented by the
`kern.geom.confxml' sysctl(8) MIB.
NB: Only really useful for external scripts that use the API and run as
non-root; where this code is used in bsdconfig(8) and bsdinstall(8)
you are running as root so can detect even ``dangerously dedicated''
file systems that are not present in GEOM; e.g., no PART class for
a DOS filesystem written directly to disk without partition table).
+ No more use of legacy tools such as diskinfo(8) to get disk capacity
or fdisk(8) to see partitions.

that the slightly older dialog(1) requires --separate-output when using the
--checklist widget to force response to produce unquoted values (whereas in
stable/10 --checklist widget without --separate-output will only quote the
checklist labels in the response if the label is multi-word (contains any
whitespace).
Since these enhancements (see revisions 263956 and 264437) were developed
originally on 10, the --separate-output option was omitted. When merged to
stable/9, we (Allan Jude) and I found during testing that the "always-
quoting" of the response was causing things like struct interpolation to
fail (`f_struct device_$dev' would produce `f_struct device_\"da0\"' for
example -- literal quotes inherited from dialog(1) --checklist response).
To see the behavior, execute the following on stable/9 versus stable/10:
dialog --checklist disks: 0 0 0 da0 "" off da1 "" off
Check both items and hit enter. On stable/10, the response is:
da0 da1
On stable/9 the response is:
"da0" "da1"
If you use the --separate-output option, the response is the same for both:
da0
da1
So applying --separate-output on every platform until either one of two
things occurs 1) dialog(1,3) gets synchronized between stable/9, higher or
