r310342 fixed non-deterministic nvram_map_gen.awk output and thus a non-
reproducible bhnd(4) build by using a unique sort key.
Go one step further and also remove the srand() call. There's no reason
we want non-deterministic behaviour from this script.

The problem here is that the archive is too short (< 512 bytes). The
buffer routines, try to read at least 512 bytes, even when we try to
determine what format file we have, which is wrong.

VMware tries to enable this bit to avoid multiple threshold notifications
in case of multiple initiators connected to the same LUN. Unfortunately
their code sends MODE SELECT(6) request with parameter length hardcoded
for the page without any thresholds. Since we have four threshold and our
page is bigger, this attempt fails, that is correct in my understanding.
So all we can do about this now is to report proper error code and hope
VMware fix their code one day.

The libgcc __register_frame and __deregister_frame functions take a
pointer to a set of FDE/CIEs, terminated by an entry where length is 0.
In Apple's libunwind implementation the pointer is taken to be to a
single FDE. I suspect this was just an Apple bug, compensated by Apple-
specific code in LLVM.
See lib/ExecutionEngine/RuntimeDyld/RTDyldMemoryManager.cpp and
http://lists.llvm.org/pipermail/llvm-dev/2013-April/061737.html
for more detail.
This change is based on the LLVM RTDyldMemoryManager.cpp. It should
later be changed to be alignment-safe.

Now that we have our sysctl tree annotated with aggregation labels,
let's go ahead and provide a very simple utility for exporting the
sysctl tree in Prometheus' format. It can either be used in conjunction
with the Prometheus node exporter or run through inetd(8).
The reason why I'm opting for having it in the base system is because it
has a pretty strong integration with some of sysctl's innards, such as
access to iterators, name lookups, metadata and type information. As I
am investigating whether we can add histograms as native types to sysctl
as well, this integration will only get stronger as we go along. That's
why it would be safer to oversee the development of this exporter
ourselves, as opposed to having it as an external project.
This exporter is remarkably compact, especially when compared to the
official Linux binary of the Prometheus node exporter (16 KB vs 12 MB).
I guess this could be an interesting aspect for monitoring embedded
FreeBSD-based systems.

Use proper name for local variables. PDU fields' name was not changed yet.
While I'm here, make # of usable channels tunable. This eases further

When ordering SROM layout entries, we now use the unique (var_id,
rev_start, rev_end) tuple as the sort key; this fixes the previously
non-deterministic output when sorting entries with overlapping var_ids.

FC-Tape provides additional link level error recovery, and is
highly recommended for tape devices. It will only be turned on for
a given target if the target supports it.
Without this setting, we default to whatever FC-Tape setting is in
NVRAM on the card.
This can be overridden by setting the following loader tunable, for
example for isp0:
hint.isp.0.nofctape=1
sys/conf/options:
Add a new kernel config option, ISP_FCTAPE_OFF, that
defaults the FC-Tape configuration to off.
sys/dev/isp/isp_pci.c:
If ISP_FCTAPE_OFF is defined, turn off FC-Tape. Otherwise,
turn it on if the card supports it.
share/man/man4/isp.4:
Add a description of FC-Tape to the isp(4) man page.
Add descriptions of the fctape and nofctape options, as well as the
ISP_FCTAPE_OFF kernel configuration option.
Add the ispfw module and kernel drivers to the suggested
configurations at the top of the man page so that users are less
likely to leave it out. The driver works well with the included
firmware, but may not work at all with whatever firmware the user
has flashed on their card.

pause() uses a spin loop to simulate a sleep during early boot. However,
we only need this for thread0 to get far enough in the boot process to
enable timers (at which point pause() can sleep). For other kthreads,
sleeping in pause() is ok as the callout will be scheduled and will
eventually fire once thread0 initializes timers.

dtrace converts pairs of consecutive underscores in a probe name to dashes.
When dtrace -G processes relocations corresponding to USDT probe sites, it
performs this conversion on the corresponding symbol names prior to looking
up the resulting probe names in the USDT provider definition. However, in
so doing it would actually modify the input object's string table, which
breaks the string suffix merging done by recent binutils. Because we don't
care about the symbol name once the probe site is recorded, just perform the
probe lookup using a temporary copy.
