Due to an oversight in r195280, auditon(A_SETCLASS, ...) would cause a tailq
element to get added to the tailq twice, resulting in a circular tailq. This
panics when INVARIANTS are on.

The GMII control bit ETH_MAC_CR_GMII_EN_ is not documented in
LAN78xx datasheets, but from the permissively licensed header provided
by Microchip it is:
#define ETH_MAC_CR_GMII_EN (0x00080000UL ) // GMII/RGMII Selection
is that current one (mass storage device) doesn't work as it is - it
needs to be set to 0 after the LUN is configured, which is what the
cfumass rc script does. In other words: the current default does not
work, and to actually make it work it had to be set to -1 in
/boot/loader.conf.

that the map entry is wired if the caller passes the flag VM_FAULT_WIRE.
Eliminate the same assertion, but spelled differently, at the end of
vm_fault_hold() and vm_fault_populate(). Repeat the assertion only if the
map is unlocked and the map lookup must be repeated.

This one call to getaddrinfo() did not adhere to the common idiom
of storing the result into a second res0 variable, which is later freed.

strncpy did not guarantee NUL termination of the "stack" string.
Use strlcpy instead. While I'm here, avoid unnecessary memset

"Developer mode" (passing of "-dev" options), which enables debugging
features on compilation error, used to dim lines unrelated to error.
That proved distracting and feedback from testers also confirmed that
simply highlighting the line the compiler complains about is enough.

dwatch allows you to customnize the predicate (condition) for when
information is displayed. The DTrace syntax for this is:
probe[, ...] /predicate/ { [actions] }
But if predicate is something like "*args[1]!=NULL" to test that
the first pointer in an array is non-NULL, the syntax produced is:
probe[, ...] /*arg1!=NULL/ { [actions] }
The issue being that "/*" is the beginning of a comment and thus
the following error is emitted:
dtrace: failed to compile script /dev/stdin:
line 535: /* encountered inside a comment
This patch adds whitespace around the argument given to -t,
producing:
probe[, ...] / *arg1!=NULL / { [actions] }

This reduces the CPU cycle wastage on power9, which is SMT4. Any idle
thread that's spinning is simply starving working threads on the same core
of valuable resources.
This can be reduced further by taking more advantage of the PSSCR supported
states, as well as permitting state loss, as is currently done for power8.
The currently implemented stop state is the lowest latency, which may still
consume resources.
The sleep for I/O completion during an NFSv4.1 pNFS layout recall used
the wrong event value and could result in the "[nfscl]" thread hung
for the mount.
This patch fixes the event to be the correct.
This bug will only affect NFSv4.1 pnfs mounts and only when the server
does a layout recall callback, so it won't affect many. Without the patch,
a mount without the "pnfs" option will avoid the problem.
Found during testing of the pNFS server.

vendor provided pmu-events tables and sundry cleanups.
The vendor pmu-events tables provide counter descriptions, default
sample rates, event, umask, and flag values for all the counter
configuration permutations. Using this gives us:
- much simpler kernel code for the MD component
- helpful long and short event descriptions
- simpler user code
- sample rates that won't overload the system
Update man page with newer sample types and remove unused sample type.
