cxgbe(4): Fix netmap rx behavior with nm_split_rss
The driver should look for active queues and one potential default-queue
in both halves of the split instead of stopping at the first valid
default-queue.

powerpc: add a best-effort SMP time base sync for G5's that need it
There's no timebase freeze platform routine registered on my dual 2.3GHz
G5 PPC970FX Apple PowerMac.
For platforms without an explicit timebase freeze/unfreeze, we'll have to
make do with what we have - which for now is an explicit hand-crafted
spinlock/rendezvous method.
* For existing platforms, they'll still continue to clock freeze /
rendezvous; albeit with some stronger atomic bits now (from jhibbits@.)
* Instead of the fallback being "no timesync", implement a
best-effort one which does a similar rendezvous barrier between
BSP and APs, but instead of freeze/unfreeze the first instruction
after the CPUs all register they're ready is to set the timebase.
This has resulted in many reboots of my Powermac G5 dual-socket device
correctly starting and running in SMP mode.

bnxt: don't set media status if link is down
When the link is down don't set flags other than IFM_AVALID & IFM_ETHER
This avoids `media: Ethernet autoselect (Unknown <full-duplex>)` on ifconfig

ipfw: don't use the upper half lock to walk dynamic states buckets
The lock is sleepable and we can't grab it in dyn_tick(). Use the
individual bucket locks instead.

arm64/vmm: Simplify vmmpmap_remove()
This function handles invalid intermediate PTP entries, but there's no
reason for this: the passed range should be mapped. In particular, we
assert that all L3 entries encountered are mapped. So let's simplify
the code a bit. No functional change intended.

bhyve: Use PCIOCGETCONF to find the host LPC bridge
pci_host_read_config() requires write access to /dev/pci so cannot be
used with unprivileged bhyve. The lpc init code uses it to find the
host system's LPC bridge device and so was generating warnings with
bhyve running as a non-root user.
Refactor the implementation to use PCIOCGETCONF instead, which doesn't
require any special privileges. This isn't formally necessary, as we
only care about copying the host system's identifiers in order to
support Intel GPU passthrough (see commit f4ceaff56ddaa), but it's
straightforward and lets an unprivileged user run bhyve without seeing
warnings about failing to open /dev/pci with write permissions.

Add pdrfork to OpenBSM
It's necessary for auditd to be able to log its events. Note that the
recently added pdwait() syscall is only auditable because an audit event
of that name was preemptively added back in 2012.

witness: Provide facility to print detailed lock tree
When witness(4) detects lock order reversals (LORs), it prints
information about the stack trace which caused the LOR. If available,
it can also print information about the first stack trace which
established the other lock ordering. However, it only does this for
"simple" LORs where the two locks in question were directly locked
in the opposite order. When the lock order was established through
a more complex pattern of intermediate locks, WITNESS only prints
the stack trace where it detected the LOR.
This commit provides new functionality to provide more verbose
information about the lock chain(s) which established the lock
ordering. The new functionality can be disabled by setting the
debug.witness.trace sysctl/tunable to 1. The new functionality
is also available through the debug.witness.badstacks sysctl,
which has been modified to always show the more verbose
information.
