Before, preloaded objects, if not listed as needed for any normally
linked objects, were silently ignored.
Preloaded objects are printed with the `[preloaded]` herald. The list
includes the objects not listed explicitly as recursive dependencies of
the main object, effectively dsos loaded by LD_PRELOAD mechanism.
vdso is listed as well, since it is not needed by anything.
Since there is no DT_NEEDED entry for LD_PRELOADed objects, they are
usually printed using LD_TRACE_LOADED_OBJECTS_FTM2 format due to the
failure of the heuristic based on the presence of the 'lib' prefix.

The license of the firmware matches the previous rtwnfw(4) firmware
files (modulo a Copyright year) and you can find a copy in
sys/contrib/dev/rtw88fw/LICENCE.rtlwifi_firmware.txt.
Add build infrastructure to create the .ko files but do not yet hook
it up to the build until all parts are in the tree.
While our version of the driver has knowledge about the incapablity
of DMA above 4GB we do see errors if people have more than that
often already showing when laoding firmware.
The problem for that is currently believed to be outside this driver
so importing it anyway for now.
Given the lack of full license texts on non-local files this is
imported under the draft policy for handling SPDX files (D29226). [1]

uart(4): Add a concept of "unique" serial devices
FreeBSD detects serial ports twice: First, very early in the boot
process, in order to obtain a usable console; and second, during
the device probe/attach process. When a UART is discovered during
device probing, FreeBSD attempts to determine whether it is a
device which was already being used as a console; without this,
the console doesn't work in userland.
Unfortunately it's possible for a UART to be mapped to a different
location in memory when it is discovered on a bus than it has when
it is announced via the ACPI SPCR table; this breaks the matching
process, which relies on comparing bus addresses.
To address this, we introduce a concept of "unique" serial devices,
i.e. devices which are guaranteed to be present *only once* on any
system. If we discover one of these during device probing, we can
match it to a same-PCI-vendor-and-device-numbers console which was
announced via the ACPI SPCR table, regardless of the differing bus
addresses.
At present, the only unique serial device is the "Amazon PCI serial
device" (vendor 0x1d0f, device 0x8250) found in some EC2 instances.
This unbreaks the serial console on those systems.

vm_phys: check small blocks to finish allocation
In vm_phys_alloc_queues_contig, in the case that a sequence of
max-order blocks are sought to fulfill an allocation, a sequence is
ruled out if it does not have enough max-order blocks to satisfy the
allocation. However, there may be smaller blocks of free memory that
follow the last max-order block in the sequence, and they may be big
enough to complete the allocation request, so check for that
possibility before giving up on that block sequence.

Historically 32-bit Linuxulator under amd64 emulated the real i386

so we didn't fit more than one of these in but needed more space.
