Turn on FC-Tape by default in the isp(4) driver.
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

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.

Don't spin in pause() during early boot for kthreads other than thread0.
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.

Avoid modifying the object string table when patching USDT probes.
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.

Do not clear KN_INFLUX when not owning influx state.
For notes in KN_INFLUX|KN_SCAN state, the influx bit is set by a
parallel scan. When knote() reports event for the vnode filters,
which require kqueue unlocked, it unconditionally sets and then clears
influx to keep note around kqueue unlock. There, do not clear influx
flag if a scan set it, since we do not own it, instead we prevent scan
from executing by holding knlist lock.
The knote_fork() function has somewhat similar problem, it might set
KN_INFLUX for scanned note, drop kqueue and list locks, and then clear
the flag after relock. A solution there would be different enough, as
well as the test program, so close the reported issue first.
