acpidump IVRS table format: change 'IOMMUId' into 'IOMMU DeviceId'
and apply the consistent format for device ids used in other IVRS
elements. The field seems to be the PCI Device ID of the IOMMU itself,
instead of an abstract unit ID.

arm64 pmap: eliminate a redundant variable
Moreover, if we attempt an L2 promotion on the kernel pmap from

geli: allocate a UMA pool earlier
The functions g_eli_init_uma and g_eli_fini_uma are used to trace
the number of devices in GELI. There is an issue where the g_eli_create
function may fail before g_eli_init_uma is called, however
g_eli_fini_uma is still executed in the fail path. This can
incorrectly decrease the device count to zero, potentially leading to
the UMA pool being freed. Accessing the device after the pool has been
freed causes a system panic.
This commit resolves the issue by ensuring devices count is increassed
eariler.

With the commit of D44903 we no longer need the SAD option. Instead all stacks that

devctl: Disable the boottime optimization of suppressing NOMATCH
The usb bus code (uhub) doens't present the same information to devctl
as it does to the NOMATCH events it generats. As such, devmatch fails to
find USB devices on boot when NOMATCH events are optimized out. Since
the savings of boot time is relatively trivial for all but the most
demanding boot environments, disable it by default until this issue is
fixed.

libcxxrt: allow build with gcc13 and --no-undefined-version
GCC 13 supports _Float16 and __int128 on fewer architectures than clang
and thus libcxxrt compiled with gcc13 is sometimes missing related
symbols. Hack around this by explicitly appending --undefined-version
to LDFLAGS in problematic cases.

sound: Fix oss_sysinfo->numcards
According to the OSS manual, oss_sysinfo->numcards holds the number of

whose value is assigned to oss_sysinfo->numcards, holds the number of

sound: Remove nmix variable from mixer_oss_mixerinfo()
nmix is used to compare against oss_mixerinfo->dev, which is a
user-supplied value to select the mixer device (if not -1, in which case
we'll select the default one) we want to fetch the information of. It is
also used to set oss_mixerinfo->dev in case it is -1.
However, nmix is at best redundant, since we have the loop counter
already (i), and confusing at worst.
For example, suppose a system with 3 mixer devices. We call
SNDCTL_MIXERINFO with oss_mixerinfo->dev=1, meaning we want to get
information for /dev/mixer1. Suppose /dev/mixer0 detaches while inside
the loop, so we'll hit the loop's "continue" case, and nmix won't get
incremented (i.e will stay 0 for now). At this point nmix counts 1
device less, so when it reaches 1, we'll be fetching /dev/mixer2's
information instead of /dev/mixer1's.
This is also true in case the mixer device disappears prior to the call
