Note: it is a good idea to run this against a physical drive to
exercise the physio fast path (ie. lio_kqueue /dev/<something safe>)
This will ensure op's counting per LIO request is correct. It is
currently broken the above patch fixes it.

Failure to do this will result in following ata_pio_read() calls walking
off the end of the read buffer.
This resolves the "memory modified after free" panics common with Thinkpads
and CD/DVD drives.

running for the full 31 seconds.
Handling this case eliminates long hangs on resume on some systems.

against a disk as the argument. If you don't it will use a temp file.
The raw disk will use the kernel physio fast path method until the
max number of pending op's is reached then it will queue them. File
system op's are always queued. This is more important with LIO since
operation can get split across and accounting of op's is broken with LIO.
Note that this was broken when locking was added to kqueue (ie. 5.3)
My fix needs to be better integrated with FreeBSD.
Next is an LIO test and implementation.

to hit this case when /usr is remote and thus hasn't been mounted (since
you're supposed to have /var before mounting remote file systems).
Normal machines that don't have a /var for some reason will have /usr
already available because it's local.
and the X1034A (quad HME; QFE) cards the X1033A (single HME) don't have a
PCI-PCI-bridge so we can't rely on the PCI slot number being useable as
index for the network address to read from the VPD on the latter. Use
the end tag to determine whether it is a QFE VPD with 4 NAs and only use
the slot number as index in this case.

automaticly created at boot. There's no need to maintain a list of
files and permissions in multiple places. This also means binary
updates won't stomp on log files.
For the record, utmp is created in etc/rc.d/cleanvar, wtmp and lastlog
in etc/rc.d/var, and the reset via etc/rc.d/newsyslog.
- Enable it by default, running newsyslog with -CN which creates files
that have the C flag specified in /etc/newsyslog.conf.
- Remove the "newsyslog -CC" call from etc/rc.d/var and the check for
newsyslog.
- Add the C flag to entries in /etc/newsyslog.conf that are currently
installed as part of the base system.
There are two effects from this change:
- Users who delete default syslog files to stop logging to them
will need to set newsyslog_enable=NO in rc.conf or remove the C
flag from those file in /etc/newsyslog.conf or they will come back
on the next boot.
- Diskless systems now create the same set of files that ordinary
systems have by default instead of every file in newsyslog.conf.

- Also create /var/log/wtmp if missing.
- Attempt to create these files unless populate_var is NO rather then
only when /var is empty or populate_var=YES.

attached to a parent interface we use its mutex to lock the softc. This
means that in several places like carp_ioctl() we lock softc conditionaly.
This should be redesigned.
To avoid LORs when MII announces us a link state change, we schedule
a quick callout and call carp_carpdev_state_locked() from it.
Initialize callouts using NET_CALLOUT_MPSAFE.
