were not. This is useless config because any userspace IB code requires
kernel support. So enable modules build by default.

The current uname is branch-cXXXX-gHASH
Three changes to make uname more useful.
1. Move from using git rev-list --count to git rev-lis --count --first-parent
since that gives a better, incrementing number.
2. Report this count as 'nXXXXX' rather than 'cXXXXX' because c is part of
a hash and we've changed the sematnics of XXXXX
3. Remove g to make HASH cut and pastable.
Durting review, #1 & #3 had the largest consensus. There was a diversity of
opinion on #2, but on the whole it was positive so I'll acknowledge the dissent,
but move forward with something seems to have support since the dissent was all
about what letter to use where I chose 'n'.

This code implements a version of the devres framework found
working for various iwlwifi use cases and also providing functions
for ttm_page_alloc_dma.c from DRM.
Part of the framework replicates the consumed KPI, while others
are internal helper functions.
In addition the simple devm_k*malloc() consumers were implemented
and kvasprintf() was enhanced to also work for the devm_kasprintf()
case.
Addmittingly lkpi_devm_kmalloc_release() could be avoided but for
the overall understanding of the code and possible memory tracing
it may still be helpful.
Further devsres consumer are implemented for iwlwifi but will follow
later as the main reason for this change is to sort out overlap with
DRM.

Implement linux firmware KPI compat code.
This includes: request_firmware() request_firmware_nowait(),
request_firmware_direct(), firmware_request_nowarn(),
and release_firmware().
Given we will try to map requested names from natively ported
or full-linuxkpi-using drivers to a firmware(9) auto-loading
name format (.ko file name and image name matching),
we quieten firmware(9) and print success or failure (unless
the _nowarn() version was called) in the linuxkpi implementation.
At the moment we try up-to 4 different naming combinations,
with path stripped, original name, and requested name with '/'
or '.' replaced.
We do not currently defer loading in the "nowait" case.

This node is part of an A10-NSP (L2-BSA) development.
Carrier networks tend to stack three or more tags for internal
purposes and therefore hiding the service tags deep inside of the
stack. When decomposing such an access network frame, the processing
order is typically reversed: First distinguish by service, than by
other means.
This new netgragh node allows to bring the relevant VLAN in front (to
the out-most position). This way other netgraph nodes (like ng_vlan)
can operate on this specific type.

Use the existing legacy PCI driver as the basis for shared code
between the legacy and modern PCI drivers. The existing virtio_pci
kernel module will contain both the legacy and modern drivers.
Changes to the virtqueue and each device driver (network, block, etc)
for V1 support come in later commits.
Update the MMIO driver to reflect the VirtIO bus method changes, but
the modern compliance can be improved on later.
Note that the modern PCI driver requires bus_map_resource() to be
implemented, which is not the case on all archs.
The hw.virtio.pci.transitional tunable default value is zero so
transitional devices will continue to be driven via the legacy
driver.

While here change the way to get the linux version, simply hardcode
the value in sys/dts/freebsd-compatible.dts and use awk to get that
to put it in the CFLAGS.
As a bonus we now have the bindings docs available
in sys/contrib/device-tree/Bindings/ so no need to link to the Linux repo
