* Obtain/release schedlock around calls to calcru.
* Sort switch cases which do not cascade per style(9).
* Sort local variables per style(9).
* Remove "superfluous" whitespace.
* Cleanup handling of NULL uap->tp in clock_getres(). It would probably
be better to return EFAULT like clock_gettime() does by passing the
pointer to copyout(), but I presume it was written to not fail on
purpose in the original code. I'll defer to -standards on this one.

There are still issues with not detaching from cam correctly such that
upon a device detach there's an invalid pointer dereference from the
later call to cam_rescan().
that are on a CISS bus to be exported up to CAM and made available as normal
devices. This will typically add one or two buses to CAM, which will be
numbered starting at 32 to allow room for CISS proxy buses. Also, the CISS
firmware usually hides disk devices, but these can also be exposed as 'pass'
devices if you set the hw.ciss.expose_hidden_physical tunable.

where it is known to detect a problem but the problem is not very easy
to fix. The warning became very common recently after a call to calcru()
was added to fill_kinfo_thread().
Another (much older) cause of "negative times" (actually non-monotonic
times) was fixed in rev.1.237 of kern_exit.c.
Print separate messages for non-monotonic and negative times.
kvm_getprocs() will provide useful information if it can, or *it*
will provide a zero value if it can not find something appropriate.

from exit1(). sched_exit() must be called unconditionally from exit1().
It was called almost unconditionally because the only exits on system
shutdown if at all.
(2) Removed the comment that presumed to know what sched_exit() does.
sched_exit() does different things for the ULE case. The call became
essential when it started doing load average stuff, but its caller
should not know that.
(3) Didn't fix bugs caused by bitrot in the condition. The condition was
last correct in rev.1.208 when it was in wait1(). There p was spelled
curthread->td_proc and was for the waiting parent; now p is for the
exiting child. The condition was to avoid lowering init's priority.
It should be in sched_exit() itself. Lowering of priorities is broken
in other ways in at least the 4BSD scheduler, and doing it for init
causes less noticeable problems than doing it for for shells.

least the pci device unloadable
- Use ttymalloc() rather than a plain malloc to allocate the
rp->rp_tty ttys. This is now required due to the recent locking
changes to ttys and prevents a panic due to locking an unitialized
t_mtx.
- Allow the pci driver to be unloaded. This involved moving
the call rp_releaseresource() to the end of rp_pcireleaseresource(),
since rp_pcireleaseresource() uses ctlp->dev, which is freed
by rp_releaseresource().
- Allow the generic part of the driver to be unattached by providing
a hook to cancel timeouts.

These changes allow tftpd to interact with pxelinux.bin from the syslinux
package.
Whilst the path reducing code doesn't properly handle situations where the
path component before the "/../" is a symlink to (say) ".", I would suggest
that it does the right thing in terms of the clients perception of what
their path string actually represents. This seems better than using
realpath() and breaking environments where symlinks point outside of the
directory hierarchy that tftpd is configured to allow.
