Add a message about failed GPT entry checksum error to both. This
was inadvertantly deleted in the switch to one entry at a time
processing.

conversion. Because pmap_extract() acquires the PTE mutex, a "locking
against myself" panic is triggered if the cache routine gets called in
a context where the mutex is already held.
In the pmap, all calls to HitSyncDCache() are for a whole page. Add a
new cache routine, HitSyncDCachePage(), which gets both the va and the
pa of a page. This removes the need of the va->pa conversion. The new
routine has the same signature as SyncDCachePage(), allowing reuse of
the same routine for cache implementations that do not need differences
between "Hit" and non-"Hit" routines.

This should fix some of the odd termination errors people have been seeing
(vmctl status showing running VMs after they have exited/crashed, and
invalid instruction panics on vmptrld during certain races)
This diff also implements dropping the biglock when running a VCPU, and
reacquiring the lock as needed based on the type of exit (normal vs.
external interrupt)

Otherwise the PHY goes undetected on the slave node of a dual-node
Origin 200. The PHY gets enabled by diagnostic checks but only on the
master node. As the attach code will now do the enabling, the checks can
be disabled on reboot, making reboots faster especially on IP27.
Tested on Origin 200 (IP27), Fuel (IP35 with iec), and Origin 350
(IP35 without iec).

Use the size info in struct sr_boot_volume, and not the uninitialized
info in the disklabel, when checking the GPT protective MBR. Now
both GPT and MBR formatted softraid volumes actually boot.
As a bonus add prototype for gpt_chk_mbr().

This patch adds a new driver for use of virtio-console devices as
ttys. It's still in an early state and not compiled by default, yet.
Currently it is only wired into amd64. i386 is still missing.

function into two parts: pvbus_identify() to scan the CPUID registers
