Jean-Sébastien Pédron 83fbb296a9 vt(4): Store a rectangle for the drawable area, not just the top-left corner
This allows backends to verify they do not draw outside of this area.

Davide Italiano 266d427bc0 Rather than using an hardcoded reclaim age, rely on an LRU-like approach
for dirhash cache, setting a target percent to reclaim (exposed via
SYSCTL). This allows to always make some amount of progress keeping the maximum
reclaim age dynamic.

Jean-Sébastien Pédron 0878762c5b vt(4): Take font offset into account in vt_is_cursor_in_area()
This fixes a "General protection fault" in vt_vga, where
vt_is_cursor_in_area() erroneously reported that the cursor was over the
text. This led to negative integers stored in "unsigned int" and chaos.

Adrian Chadd a39b467a26 i915 driver - enable opregion handle; program CADL.
add opregion handling for drm2 - which exposes some ACPI video configuration
pieces that some Lenovo laptop models use to flesh out which video device
to speak to.  This enables the brightness control in ACPI to work these models.

The CADL bits are also important - it's used to figure out which ACPI
events to hook the brightness buttons into.  It doesn't yet seem to work
for me, but it does for the OP.

Tested:

* Lenovo X230 (mine)
* OP: ASUS UX51VZ

tunables to modify the default cpu topology advertised by bhyve.

Also add a tunable "hw.vmm.topology.cpuid_leaf_b" to disable the CPUID
leaf 0xb. This is intended for testing guest behavior when it falls back
on using CPUID leaf 0x4 to deduce CPU topology.

The default behavior is to advertise each vcpu as a core in a separate soket.

Adrian Chadd 062cf7d90a Shut down RX before TX - in theory, this should make the chip less likely
to get upset.

The Qualcomm Atheros reference design code goes through significant
hacks to shut down RX before TX.  It doesn't even try do do it in the
driver - it actually makes the DMA stop routines in the HAL shut down
RX before shutting down TX.

So, to make this work for chips that aren't the AR9380 and later, do
it in the driver.  Shuffle the TX stop/drain HAL calls to be called
*after* the RX stop HAL call.

Tested:

* AR5413 (STA)
* AR5212 (STA)
* AR5416 (STA)
* AR9380 (STA)
* AR9331 (AP)
* AR9341 (AP)

TODO:

* test ar92xx series NIC and the AR5210/AR5211, in case there's something
  even odder about those.
