It does extremely useful things like execute sendmail and spew dubiously
accurate factoids.

From the feedback, it seems like it is an essential utility in a modern unix
and not at all a useless bikeshed.  How do those Linux people live without it?

When looking for cpu with the same OPP starts from the root /cpus node
so each instance of cpufreq_dt will now each cpu with the same operating
point.
Also test that the node we are testing have the property "device_type" set
to be equal to "cpu".
While here add more debug printfs (off by defaults).

These support outdated or obsolete ISA WAN (T1/E1) sync serial cards,
and these drivers haven't really been touched (other than in tree-wide
sweeps to keep them building) for 15+ years.

Related PCI devices ce and cp are still in the tree, with deprecation
proposed in D23928.

Hexdump test was failling on big endian systems when testing decimal, octal
and hexa outputs as the tests were designed on a little endian system. This
revision adds the two distinct flavors of output expected and determines at
runtime which to compare against.

This issue was observed on a PowerPC64 machine with an Adaptec RAID
Controller with PCI device ID 0x028d, where sense data was causing a
buffer overflow because of wrong max sense length logic.

We don't produce these anymore as of r356797, remove the remnant in
generate-ucl.sh that accounted for them. This isn't strictly necessary, but
future work is needed for the various packages that can be generated on a
lib build.

Namely, we may produce -development packages for private/internal libs that
should be installed but won't have the base FreeBSD-libfoo pkg to depend on
because it's internal (e.g. liby, libpmcstat, libifconfig) but we want the
headers installed. It may be a better move to just shove these into
-runtime-development instead, but if not then we've just simplified the
cases that need to take private/internal libs into account.

This allows libinput to disable touchpads when the lid is closed and
various desktop environments can show power-off dialogs when the power

cross-platform solution is nicer.

GCC points out a couple levels down in convert_to_features that this may be
used uninitialized. Indeed, this is true- initialize it to NULL so that we
at least deref a null pointer.

When generating an cloned interface instance in edsc_clone_create(),
generate a MAC address from the FF OUI with ether_gen_addr(). This allows us
to have unique local-link addresses. Previously, the MAC address was zero.

Lite.  Nowadays it's trivial to find the explanation, such as at
https://www.deseret.com/2000/2/27/19493013/blackthorn-winds-make-bushes-bud.
It doesn't seem appropriate to replace it with an explanation.

This fixes a regression from r358363.

The new structure is copy-on-write. With the assumption that path lookups are
significantly more frequent than chdirs and chrooting this is a win.

This provides stable root and jail root vnodes without the need to reference
them on lookup, which in turn means less work on globally shared structures.
Note this also happens to fix a bug where jail vnode was never referenced,
meaning subsequent access on lookup could run into use-after-free.

network layer has evolved since then, and this won't compile there.

The sbuf API has evolved since 8, as have many others. The other API sweeps
didn't make the changes conditional, so this is now noise.
