bc96dccc69 Fix final bugs in memory barriers on PowerPC:
- Use isync/lwsync unconditionally for acquire/release. Use of isync
  guarantees a complete memory barrier, which is important for serialization
  of bus space accesses with mutexes on multi-processor systems.
- Go back to using sync as the I/O memory barrier, which solves the same
  problem as above with respect to mutex release using lwsync, while not
  penalizing non-I/O operations like a return to sync on the atomic release
  operations would.
- Place an acquisition barrier around thread lock acquisition in
  cpu_switchin().

6632cb429f Disable setting the MII port speed.
This seems to break at least my test board here (AR71xx + AR8316 switch
PHY).  Since I do have a whole sleuth of "normal" PHY boards (with
an AR71xx on a normal PHY port), I'll do some further testing with those
to determine whether this is a general issue, or whether it's limited
to the behaviour of the "fake" dedicated PHY port mode on these atheros
switches.

b8be27bf29 Revert part of r234723 by re-enabling the SMP protection for
intr_bind() on x86.
This has been requested by jhb and I strongly disagree with this,
but as long as he is the x86 and interrupt subsystem maintainer I will
follow his directives.

The disagreement cames from what we should really consider as a
public KPI. IMHO, if we really need a selection between the kernel
functions, we may need an explicit protection like _KERNEL_KPI, which
defines which subset of the kernel function might really be considered
as part of the KPI (for thirdy part modules) and which not.
As long as we don't have this mechanism I just consider any possible
function as usable by thirdy part code, thus intr_bind() included.

bdaa925cc7 Fix <stdatomic.h> after clang decided to rename all of its builtins to include

but I don't recommend using them because they are very poorly designed.

df76012c5b - correct a bug in pcap_dispatch(): a count of 0 means infinity.
- in pcap_dispatch(), issue a prefetch on the buffer before the
  callback, this may save a little bit of time if the client
  is very fast.

- in pcap_inject(), use a fast copy routine, which also helps
  saving a few nanoseconds with fast clients.

57d07ca9f0 When callout_reset_on() cannot immediately migrate a callout since it
is running on other cpu, the CALLOUT_PENDING flag is temporarily
cleared. Then, callout_stop() on this, in fact active, callout fails
because CALLOUT_PENDING is not set, and callout_stop() returns 0.

Now, in sleepq_check_timeout(), the failed callout_stop() causes the
sleepq code to execute mi_switch() without even setting the wmesg,
since the switch-out is supposed to be transient. In fact, the thread
is put off the CPU for full timeout interval, instead of being put on
runq immediately.  Until timeout fires, the process is unkillable for
obvious reasons.

Fix this by marking the migrating callouts with CALLOUT_DFRMIGRATION
flag. The flag is cleared by callout_stop_safe() when the function
detects a migration, besides returning the success. The softclock()
rechecks the flag for migrating callout and cancels its execution if
the flag was cleared meantime.

6107adc3f5 Relax restriction on direct tx to child ports
Lagg(4) restricts the type of packet that may be sent directly to a child
port, to avoid undesired output from accidental misconfiguration.
Previously only ETHERTYPE_PAE was permitted.

BPF writes to a lagg(4) child port are presumably intentional, so just
allow them, while still blocking other packets that should take the
aggregation path.

85f6230a1d Added D_TRACKCLOSE to sndstat_cdevsw to fix the situation when
another process is in open() or stat() for the device node, then
close() from the owning process does not result in cdevsw close
method call. This fixes the pemanent "Device busy" seen.

Changed the sndstat_lock from mutex to sx.  This allows to extend
the region covered by the lock, to include the uiomove() call in
sndstat_read() and bufptr increment. This fixes the "panic:
