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
button is pressed. While the latter is doable with devd a
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.

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.

Also, inline/remove now empty or trivial macros. CAM has evolved enough this
code couldn't work there anyway, and the API sweeep commits made since then were
made unconditional.
Eliminate code for old versions, inline pci_find_cap instead of relying on
compat ifdef.
This commit should have been combined with r358488 before pushing it in.
these look to be cut and pasted from other drivers since this driver was
committed to FreeBSD 7-current and MFC'd to FreeBSD 6. The ones for FreeBSD 4
and 5 likely never were working...
On Linux the valid range of priorities for the SCHED_FIFO and SCHED_RR
scheduling policies is [1,99]. For SCHED_OTHER the single valid priority is
0. On FreeBSD it is [0,31] for all policies. Programs are supposed to
query the valid range using sched_get_priority_(min|max), but of course some
programs assume the Linux values are valid.
This commit adds a tunable compat.linux.map_sched_prio. When enabled
sched_get_priority_(min|max) return the Linux values and sched_setscheduler
and sched_(get|set)param translate between FreeBSD and Linux values.
Because there are more Linux levels than FreeBSD levels, multiple Linux
levels map to a single FreeBSD level, which means pre-emption might not
happen as it does on Linux, so the tunable allows to disable this behaviour.
It is enabled by default because I think it is unlikely that anyone runs
real-time software under Linux emulation on FreeBSD that critically relies
on correct pre-emption.
This fixes FMOD, a commercial sound library used by several games.

With powerd_flags="-N", this makes powerd(8) exclude "nice" time when
computing the CPU utilization. This makes it possible to prevent
CPU-intensive "background" processes from spinning up the CPU.
Note that only *userland* CPU usage belonging to "nice" processes is
excluded; we do not track whether time spent in the kernel is on behalf
of nice or non-nice processes, so kernel-intensive nice processes can
still result in the CPU being sped up.

Now that we no longer have GCC 4.2.1 in the tree and can assume FreeBSD
is being built with a C++11 compiler available, we can use BSDL dtc
unconditionally and retire the GPL dtc.
GPL dtc now has FreeBSD CI support via Cirrus-CI to help ensure it
continues to build/work on FreeBSD and is available in the ports tree
if needed.
The copy of (copyfree licensed) libfdt that we actually use is in
sys/contrib/libfdt so the extra copy under contrib/dtc/libfdt can be
removed along with the rest of the GPL dtc.
