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.

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.

* Lenovo X230 (mine)

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.

946d0288f2 vt(4): Fix cursor handling in vt_flush()
There were situations where the cursor was not erased/redrawn or its
position was marked as dirty even though it's not displayed. The code is
now more straightforward.

At the same, add a function to determine if the cursor covers a given
area. This is used by backends to know if they need to draw the cursor.

This new function should be paired with a new state in struct vt_device,
called vd_mshown, which indicates if the cursor should be displayed.
This again simplifies vd_bitblt_text_t callback's API.
