a98ff31738 DTrace: re-merge remainder of r249367 (original from Illumos).
Bring back some important fixes from Illumos:

3022 DTrace: keys should not affect the sort order when sorting by value
3023 it should be possible to dereference dynamic variables
3024 D integer narrowing needs some work

We particularly avoid the LD_NOLAZYLOAD changes that Illumos made
as those don't apply to FreeBSD and were causing problems in
interactive mode.

69114bc0da Synchronize device cache on close only if there were some write operations.
While these operations are not really needed otherwise, at least for SCSI
they may cause extra errors if some other initiator holds write exclusive
reservation on the LUN (SYNCHRONIZE CACHE handled as "write" operation).

d3221f8556 At some point after stable/7 the ACPI and ISA interfaces to the IPMI controller
no longer have the parent in the device tree.  This causes the identify
function in ipmi_isa.c to attempt to probe and poke at the ISA IPMI interface

Move the check for ipmi_attached out of the ipmi_isa_attach function and into
the ipmi_isa_identify function.  Remove the check of the device tree for
ipmi devices attached.

This probing appears to make Broadcom management firmware on Dell machines
crash and emit NMI EISA warnings at various times requiring power cycles
of the machines to restore.

Bump MAX_TIMEOUT to 6 seconds as a hack for super slow IPMI interfaces that
need longer to respond to our intial probes on startup.

Tested on Dell R410, R510, R815, HP DL160G6

This is MFC candidate for 9.2R

caf20efcde Add support for packet-sniffing tracers to cxgbe(4). This works with
all T4 and T5 based cards and is useful for analyzing TSO, LRO, TOE, and
for general purpose monitoring without tapping any cxgbe or cxl ifnet
directly.

Tracers on the T4/T5 chips provide access to Ethernet frames exactly as
they were received from or transmitted on the wire.  On transmit, a
tracer will capture a frame after TSO segmentation, hw VLAN tag
insertion, hw L3 & L4 checksum insertion, etc.  It will also capture
frames generated by the TCP offload engine (TOE traffic is normally
invisible to the kernel).  On receive, a tracer will capture a frame
before hw VLAN extraction, runt filtering, other badness filtering,
before the steering/drop/L2-rewrite filters or the TOE have had a go at
it, and of course before sw LRO in the driver.

There are 4 tracers on a chip.  A tracer can trace only in one direction
(tx or rx).  For now cxgbetool will set up tracers to capture the first
128B of every transmitted or received frame on a given port.  This is a
small subset of what the hardware can do.  A pseudo ifnet with the same
name as the nexus driver (t4nex0 or t5nex0) will be created for tracing.
The data delivered to this ifnet is an additional copy made inside the
chip.  Normal delivery to cxgbe<n> or cxl<n> will be made as usual.

/* watch cxl0, which is the first port hanging off t5nex0. */
# cxgbetool t5nex0 tracer 0 tx0  (watch what cxl0 is transmitting)
# cxgbetool t5nex0 tracer 1 rx0  (watch what cxl0 is receiving)
# cxgbetool t5nex0 tracer list
# tcpdump -i t5nex0   <== all that cxl0 sees and puts on the wire

If you were doing TSO, a tcpdump on cxl0 may have shown you ~64K
"frames" with no L3/L4 checksum but this will show you the frames that
were actually transmitted.

/* all done */
# cxgbetool t5nex0 tracer 0 disable
# cxgbetool t5nex0 tracer 1 disable
# cxgbetool t5nex0 tracer list
# ifconfig t5nex0 destroy

The BSD-licensed patch(1) command has matured and it's behaviour
can be considered equivalent to the older version of GNU patch
in the tree.

The switch has been extensively tested [1] and only two ports
presented regressions, which have since been fixed.

For convenience a new WITH_GNU_PATCH option is available,
but it will likely be removed in the near future.

49de4f2214 Break out the static, global LACP debug options into a per-lagg unit
sysctl tree.

* Create a net.link.lagg.X.lacp node
* Add a debug node under that for tx_test and rx_test
* Add lacp_strict_mode, defaulting to 1

tx_test and rx_test are still a bitmap of unit numbers for now.
At some point it would be nice to create child nodes of the lagg bundle
for each sub-interface, and then populate those with various knobs
and statistics.

8e94193e58 make path matching in devfs rules consistent and sane (and safer)
Before this change path matching had the following features:
- for device nodes the patterns were matched against full path
- in the above case '/' in a path could be matched by a wildcard
- for directories and links only the last component was matched

So, for example, a pattern like 're*' could match the following entries:
- re0 device
- responder/u0 device
- zvol/recpool directory

Although it was possible to work around this behavior (once it was spotted
and understood), it was very confusing and contrary to documentation.

Now we always match a full path for all types of devfs entries (devices,
directories, links) and a '/' has to be matched explicitly.
This behavior follows the shell globbing rules.

This change is originally developed by Jaakko Heinonen.
Many thanks!

- Explicitly note that the event added to monitor the child process
  preserves the fflags from the original event.
- Move the description of NOTE_TRACKERR under NOTE_TRACK as it is not a
  bit for the user to set (which is what this list pupports to be).
  Also, explicitly note that if an error occurs, the NOTE_CHILD event
  will not be generated.

In the end we never actually used the device description that we so
carefully maintained in the PCI match table. By setting the device
description after we call uart_probe(), we'll print the more user-

Replace the RESET blocks with regular functions and a reset() function that

This code generation tool is unusual and does not appear to provide much
benefit. I do not think isolating the knowledge about which modules need to
be reset is worth an almost 500-line build tool and wider scope for
variables used by the reset functions.

Also, relying on reset functions is often wrong: the cleanup should be done
in exception handlers so that no stale state remains after 'command eval'
