This geom does not immediately detach its consumer relying on the
wither-washer to do that. Since that happens asynchronously we may get
additional spoiling events. So, we need to account for that.
There are multiple options for fixing this issue like detaching
immediately or checking for G_CF_ORPHAN in g_slice_spoiled().
The most reliable and least intrusive fix seems to be setting
geom->softc to NULL on the first call and checking for NULL on
subsequent calls. This is something that the code did before r325227.

This is the extra key on 102/105-keys keyboards, located on the right
of the Left Shift key. For instance on a French layout, this is the '<'
key.
This fixes an issue where the key fires no evdev event and thus remains
inactive in an evdev/libinput-enabled X.Org server. The issue only
occurred on an AT keyboard; the same key on a USB keyboard worked fine.

It is used on each new entry addition to decide whether to whack an existing
negative entry in order to prevent a blow out in size, but the parameter was
set years ago and never revisited.
Building with poudriere results in about 400 evictions per second which
unnecessarily grab entries from the hot list.
With the new parameter there are next to no evictions of the sort.
This brings it closer to par with GENERIC64. In the future I hope to have a
GENERIC64-E and GENERIC-E kernels as Book-E analogues to the GENERIC64/GENERIC
AIM kernels.
This is needed for the HDA emulation with FreeBSD guests.

Some devices (P5040, P4080) have multiple frame managers in their DPAA

There's no good reason to treewalk the entire tree removing old OBJDIRS
and creating new ones when 'includes', 'libraries', and 'everything' are
all skipped. The only shared directory in the existing toolchain target
and world is build-tools. So handle cleaning in it directly if needed
only for the directories it wants to build.
The extra _obj/_cleanobj walks came in the initial kernel-toolchain

The newest ena-com HAL supports LLQv2 and introduces
API changes. In order not to break the driver compilation
it was updated/fixed in a following way:
* Change version of the driver to 0.8.0
* Provide reset cause when triggering reset of the device
* Reset device after attach fails
* In the reset task free management irq after calling ena_down. Admin
queue can still be used before ena_down is called, or when it is
being handled
* Do not reset device if ena_reset_task fails
* Move call of the ena_com_dev_reset to the ena_down() routine - it
should be called only if interface was up
* Use different function for checking empty space on the sq ring
(ena-com API change)
* Fix typo on ENA_TX_CLEANUP_THRESHOLD
* Change checking for EPERM with EOPNOTSUPP - change in the ena-com API
* Minor style fixes

If vdev_geom_close doesn't close the consumer, then the subsequent call
to vdev_geom_open() would be just a NOP and would always return success.
Thus, at present vdev_reopen() would always succeed for vdev_geom devices
even if the underlying provider is in error state.
The problem was introduced as a result of an optimization in rS308055.
The most significant manifistation of the problem is that
zio_vdev_io_done() --> vdev_probe() --> SPA_ASYNC_PROBE -->
spa_async_probe() --> vdev_reopen()
chain of calls and events becomes a NOP as well.
This chain is invoked when zio_vdev_io_done() detects an "unexpected"
error from the lower level I/O.
Additionally, that call path may race with SPA_ASYNC_REMOVE path because
of the asynchronous nature of them both. So, the SPA_ASYNC_PROBE may
erroneously mark a vdev as being healthy after SPA_ASYNC_REMOVE marked
it as removed.

At present, g_slice_orphan and g_slice_spoiled destroy the softc
(struct g_slicer) even before calling g_wither_geom, so there can
be active and incoming io requests at that time and g_slice_start
can access the softc.
This commit changes the code to destroy the softc only after all
providers are closed.
While there, a couple of small cleanups.

Rework the dTSEC and FMan drivers to be more like a full bus relationship,
so that dtsec can use bus_alloc_resource() instead of trying to handle the
offset from the dts. This required taking some code from the sparc64 ebus
driver to allow subdividing the fman region for the dTSEC devices.
Now that a proper sysroot is used and a separate target list, it should
be safe to skip building the initial cross-compiler.
