7217d8d1ee - Don't rely on a side effect of sched_prio() to set the initial ts_runq
for thread0.  Set it directly in sched_setup().  This fixes traps on boot
   seen on some machines.

8f93d79d05 - Handle kdb switch panics outside of mi_switch() to remove some instructions

73daf66f41 Reduce ULE context switch time by over 25%.
- Only calculate timeshare priorities once per tick or when a thread is woken
   from sleeping.
 - Keep the ts_runq pointer valid after all priority changes.
 - Call tdq_runq_add() directly from sched_switch() without passing in via
   tdq_add().  We don't need to adjust loads or runqs anymore.
 - Sort tdq and ts_sched according to utilization to improve cache behavior.

ff256d9c47 - Add an implementation of sched_preempt() that avoids excessive IPIs.
- Normalize the preemption/ipi setting code by introducing sched_shouldpreempt()
   so the logical is identical and not repeated between tdq_notify() and
   sched_setpreempt().
 - In tdq_notify() don't set NEEDRESCHED as we may not actually own the thread lock
   this could have caused us to lose td_flags settings.
 - Garbage collect some tunables that are no longer relevant.

413deb1262 Padding after EOL option must be zeros according to RFC793 but
the NOPs used are 0x01.
While we could simply pad with EOLs (which are 0x00), rather use an
explicit 0x00 constant there to not confuse poeple with 'EOL padding'.

08995e292e Enhance realpath(1) in a number of ways:
- Allow realpath to accept multiple paths on the command line.
- Add -q to suppress warnings if some paths can't be processed, and use
  getopt(3) to process flags.
- Print the path being requested rather than a possibly partially
  processed path when a failure occurs so that you can tell which of
  several passed paths did fail.

1b21ffa615 Make chflags(1) more chmod(1)-like (and more feature complete):
- Add -v to print file names as they are processed; -vv prints the flags
  change as well.
- Add -f to ignore failures with the same semantics as chflags(1), neither
  printing an error nor affecting the return code.
- Don't try to set the flags if they won't change.

I made minor cosmetic tweaks to the code in the patch.

593e717ec9 Eliminate an unnecessary test from vm_fault's delete-behind heuristic.
Specifically, since the delete-behind heuristic is never applied to a
device-backed object, there is no point in checking whether each of the
object's pages is fictitious.  (Only device-backed objects have
fictitious pages.)

this, the probe is only successful for devices that have had a
specific devclass set for them.

9d6a74eb84 Fix a mistake made during the import of the driver. Previous versions of
HPT drivers would sometimes test the value of a preprocessor definition but
not always make sure that the definition existed in the first place, leading

and it turned out to be wrong and to enable some code that doesn't work.
