952667da98 xen/efi: introduce a PV interface for EFI run time services for dom0
FreeBSD when running as a dom0 under Xen is not supposed to access the
run time services directly, and instead should proxy the calls through
Xen using an hypercall interface that exposes access to selected run
time services.

Implement the efirt interface on top of the Xen provided hypercalls.

35af933173 acpi: limit the AMDI0020/AMDI0010 workaround to an option
It appears that production versions of EPYC firmware get the _STA method right
for these nodes. In fact, this workaround breaks on production hardware by
including too many uart nodes. This work around was for pre-release hardware
that wound up not having a large deployment. Move this work around to a kernel
option since the machines that needed it have been powered off and are difficult
to resurrect. Should there be a more significant deployment than is understood,
we can restrict it based on smbios strings.

af366d353b amd64: implement strlen in assembly
The C variant in libkern performs excessive branching to find the
non-zero byte instead of using the bsfq instruction. The same code
patched to use it is still slower than the routine implemented here
as the compiler keeps neglecting to perform certain optimizations
(like using leaq).

On top of that the routine can is a starting point for copyinstr
which operates on words instead of bytes.

Tested with glibc test suite.

Sample results (calls/s):

8a51f14a78 newvers: tweak uname to be more useful
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'.

fa765ca73e LinuxKPI: implement devres() framework parts and two examples
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.

a6c2507d1b LinuxKPI: add firmware loading support
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.

cfd6422a52 netgraph/ng_vlan_rotate: IEEE 802.1ad VLAN manipulation netgraph type
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.

9da9560c4d virtio: Add VirtIO PCI modern (V1) support
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.
