Correct display of bhyve SMBIOS UUIDs with dmidecode by bumping the version.
The mixed little/big-endianness of SMBIOS UUIDs was clarified in v2.6
of the SMBIOS spec. dmidecode uses the reported version of SMBIOS to
determine the layout and what to byte-swap.
bhyve's SMBIOS reported as 2.4 though it implemented the 2.6-style of
memory layout. This resulted in dmidecode reporting a different
UUID than one passed in via the -U option.
Fix by exporting a version of 2.6.

Bump minimum linux compat version to support Centos6 ports updates for linux.
Update linux compat minimum revision to match linux-c6 now in ports. This
is a candidate for 10.1 R as it matches the current state of supported
linux compat packages in the ports tree.
Rename the tests to something more meaningful. I spent way too long
trying to get the test name right, failed, gave up and used a sequence
number instead. When I realized it wasn't because of the number of
underscores in the name that I really started to think. I didn't have
braces around the variable names ...
Thus: test_1 is now called apm_1x1_512_qcow, which gives you all you
need to run mkimg by hand.
Don't update the baseline file when the result of the test is identical
to the baseline. Since we don't run gzip with the -n option, the output
of gzip varies for identical result files if and when they are created
at different time. Ouch...
Rather than add -n and commit a 600K+ diff for the changes to all the .uu
files, it's less of a churn to uudecode and gunzip the baseline file and
compare that to the new result file to determine if the baseline file
needs to be updated.
This way, "atf-sh mkimg.sh rebase" can be run as many times as people like
and a subsequent "svn status" will not show unnecessary diffs.

Add support for QCOW version 1. Version 2 is partially implemented.
And because of that, it's entirely disabled for now. Both versions
are similar enough that a single header definition works for both
of them. The only "diverting" side-effect is that the union of the
two is larger than the official V1 header.
What this means for our V1 support is that we can't put the L1 table
adjacent to the V1 header (i.e. at offset 0x30 in the file), unless
we revert to hackery and klugery. Let's not. Instead, we align the L1
table at the cluster boundary. This is in line with the V2 layout and
perfectly ok for V1 anyway (ok -- as far as I've seen so far).
Due to the alignment, our V1 image seems to be 1 cluster larger than
the V1 image created by qemu-img (on average).
Compression of the clusters is not supported at this time.

The new naming scheme for keymap files for use with vt(4) introduced a
collision for "no" as a country code with "NO" meaning "do not load any
keymap" (which also has been the default value in etc/defaults/rc.conf
for a long time).
The result of this collision is, that "kbdcontrol -l no" will load the
Norwegian keymap, while "keymap=no" in rc.conf was interpreted as the
lower case spelling of "NO" meaning "no keyboard" (and "no.kbd" was not
loaded).
Fix this by matching only the upper-case spelling "NO" in rc.d/syscons
when deciding whether to load a keymap file.
This will lead to "no.kbd" being loaded, if the until now valid (but
non-default) spelling "no" was used in an individual rc.conf file to mean
"no keyboard". But all alternatives I could think of introduce a larger
violation of POLA ...

Improve transmit sending offload, TSO, algorithm in general.
The current TSO limitation feature only takes the total number of
bytes in an mbuf chain into account and does not limit by the number
of mbufs in a chain. Some kinds of hardware is limited by two
factors. One is the fragment length and the second is the fragment
count. Both of these limits need to be taken into account when doing
TSO. Else some kinds of hardware might have to drop completely valid
mbuf chains because they cannot loaded into the given hardware's DMA
engine. The new way of doing TSO limitation has been made backwards
compatible as input from other FreeBSD developers and will use
defaults for values not set.

Make the ARM MPCore Timer driver work with published standard FDT bindings.
We've always considered the mpcore timers to be a single monolithic device
and we defined our own fdt binding for it with our own compat string. The
published bindings treat the timers as two separate devices, a global
timer and a "timer-watchdog" device for the per-cpu private timers. Thus
our binding has two tuples in the regs property, one set of registers for
the global timer and one for the private timers. The published bindings
have two separate devices, each with a single set of registers. (Note that
we don't use the optional watchdog feature of the hardware.)
These changes add the compat strings for the published bindings. If our
own compat string appears, we expect to get two sets of memory resources.
For the published bindings, there's only one set of memory resources, and
only the private timers have an associated interrupt.
The other major change is that there can no longer be a single global var
for the softc pointer because now there may be multiple devices at
runtime. Since the global timer is used only as a timecounter and the
private timers only as eventtimers, and there will only be one of each,
those are now the pointers which are global, and the priv fields of those
structures backlink to the device softc.

Restructure the MSR handling so it is entirely handled by processor-specific
code. There are only a handful of MSRs common between the two so there isn't
too much duplicate functionality.
The VT-x code has the following types of MSRs:
- MSRs that are unconditionally saved/restored on every guest/host context
switch (e.g., MSR_GSBASE).
- MSRs that are restored to guest values on entry to vmx_run() and saved
before returning. This is an optimization for MSRs that are not used in
host kernel context (e.g., MSR_KGSBASE).
- MSRs that are emulated and every access by the guest causes a trap into
the hypervisor (e.g., MSR_IA32_MISC_ENABLE).

Fix up the EDMA RX setup path to correctly initialise and reset the RX FIFO.
The original code was .. well, slightly more than incorrect.
It showed up as stalled RX queues if the NIC needed to be frequently
reinitialised (eg during scans.)
This is inspired by work done by Matt Dillon over at the DragonflyBSD
project.
So:
* track when EDMA RX has been stopped and when the MAC has been reset;
* re-initialise the ring only after a reset;
* track whether RX has been stopped/started - just for debugging now;
* don't bother with the RX EOL stuff for EDMA - we don't need the
interrupt at all. We also don't need to disable/enable the interrupt
or start DMA - once new frames are pushed into the ring via the
normal RX path, it'll just restart RX DMA on its own.
Tested:
* AR9380, STA mode
* AR9380, AP mode
* AR9485, STA mode
* AR9462, STA mode
Fix partition alignment and image rounding when any of -P (block size),
-T (track size) or -H (number of heads) is given:
o scheme_metadata() always rounded to the block size. This is not
always valid (e.g. vtoc8 that must have partitions start at cylinder
boundaries).
o The bsd and vtoc8 schemes "resized" the image to make it match the
geometry, but since the geometry is an approximation and the size
of the image computed from cylinders * heads * sectors is always
smaller than the original image size, the partition information ran
out of bounds.
The fix is to have scheme_metadata() simply pass it's arguments to the
per-scheme metadata callback, so that schemes not only know where the
metadata is to go, but also what the current block address is. It's now
up to the per-scheme callback to reserve room for metadata and to make
sure alignment and rounding is applied.
The BSD scheme now has the most elaborate alignment and rounding. Just
to make the point: partitions are aligned on block boundaries, but the
image is rounded to the next cyclinder boundary.
vtoc8 now properly has all partitions aligned (and rounded) to the
cyclinder boundary.

history cycling (old content appeared below latest lines). This is
fixed.
Now, when the resolution changes are more lines can be shown, the
displayed area is adjusted so that, if the screen was filled with
content before, it's filled with content after as well: more history
is visible, instead of having blank lines below the previously visible
content.
