a9b89cf1c1 vm_page.c: include opt_msgbuf.h for MSGBUF_SIZE use in vm_page_startup
vm_page_startup uses MSGBUF_SIZE value for adding msgbuf pages to minidump.
If opt_msgbuf.h is not included and MSGBUF_SIZE is overriden in kernel
config, then not all msgbuf pages will be dumped.  And most importantly,
struct msgbuf itself will not be included.  Thus the dump would look
corrupted/incomplete to tools like kgdb, dmesg, etc that try to access
struct msgbuf as one of the first things they do when working on a crash
dump.

f03f7a0ca3 Correct bioq_disksort so that bioq_insert_tail() offers barrier semantic.
Add the BIO_ORDERED flag for struct bio and update bio clients to use it.

The barrier semantics of bioq_insert_tail() were broken in two ways:

 o In bioq_disksort(), an added bio could be inserted at the head of
   the queue, even when a barrier was present, if the sort key for
   the new entry was less than that of the last queued barrier bio.

 o The last_offset used to generate the sort key for newly queued bios
   did not stay at the position of the barrier until either the
   barrier was de-queued, or a new barrier (which updates last_offset)
   was queued.  When a barrier is in effect, we know that the disk
   will pass through the barrier position just before the
   "blocked bios" are released, so using the barrier's offset for
   last_offset is the optimal choice.

sys/geom/sched/subr_disk.c:
sys/kern/subr_disk.c:
	o Update last_offset in bioq_insert_tail().

	o Only update last_offset in bioq_remove() if the removed bio is
	  at the head of the queue (typically due to a call via
	  bioq_takefirst()) and no barrier is active.

	o In bioq_disksort(), if we have a barrier (insert_point is non-NULL),
	  set prev to the barrier and cur to it's next element.  Now that
	  last_offset is kept at the barrier position, this change isn't
	  strictly necessary, but since we have to take a decision branch
	  anyway, it does avoid one, no-op, loop iteration in the while
	  loop that immediately follows.

	o In bioq_disksort(), bypass the normal sort for bios with the
	  BIO_ORDERED attribute and instead insert them into the queue
	  with bioq_insert_tail().  bioq_insert_tail() not only gives
	  the desired command order during insertion, but also provides
	  barrier semantics so that commands disksorted in the future
	  cannot pass the just enqueued transaction.

sys/sys/bio.h:
	Add BIO_ORDERED as bit 4 of the bio_flags field in struct bio.

sys/cam/ata/ata_da.c:
sys/cam/scsi/scsi_da.c
	Use an ordered command for SCSI/ATA-NCQ commands issued in
	response to bios with the BIO_ORDERED flag set.

sys/cam/scsi/scsi_da.c
	Use an ordered tag when issuing a synchronize cache command.

	Wrap some lines to 80 columns.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c
sys/geom/geom_io.c
	Mark bios with the BIO_FLUSH command as BIO_ORDERED.

94222398d1 Unlike most other controllers, NS DP83815/DP83816 controllers seem
to pad with 0xFF when it encounter short frames.  According to RFC
1042 the pad bytes should be 0x00.
Because manual padding consumes extra CPU cycles, introduce a new
tunable which controls the padding behavior. Turning this tunable
on will have driver pad manually but it's disabled by default. Users
can enable software padding by setting the following tunable to
non-zero value.

dev.sis.%d.manual_pad="1"

prevented driver from working on big-endian machines. Also rewrite
station address programming to make it work on strict-alignment
architectures. With this change, sis(4) now works on sparc64 and
performance number looks good even though sis(4) have to apply
fixup code to align received frames on 2 bytes boundary on sparc64.

1b48d24533 MFp4 CH=183052 183053 183258:
In protosw we define pr_protocol as short, while on the wire
  it is an uint8_t.  That way we can have "internal" protocols
  like DIVERT, SEND or gaps for modules (PROTO_SPACER).
  Switch ipproto_{un,}register to accept a short protocol number(*)
  and do an upfront check for valid boundries. With this we
  also consistently report EPROTONOSUPPORT for out of bounds
  protocols, as we did for proto == 0.  This allows a caller
  to not error for this case, which is especially important
  if we want to automatically call these from domain handling.

  (*) the functions have been without any in-tree consumer
  since the initial introducation, so this is considered save.

  Implement ip6proto_{un,}register() similarly to their legacy IP
  counter parts to allow modules to hook up dynamically.

090c02f8bd Modify nfs_diskless.c to recognize the environment variable
boot.nfsroot.nfshandlelen and set the diskless root fs to
use NFSv3 and this file handle length when it is set. If
this environment variable is not set, the diskless root fs
will use NFSv2 and the same defaults as before. This fixes
the problem where the diskless nfs root fs had to be on a
FreeBSD server for NFSv3 to work, because it did not know
the correct file handle length and assumed the size used
by FreeBSD. Until pxeboot and loader are replaced by ones
built from commits coming soon, boot.nfsroot.nfshandlelen
will not be set by them and the diskless root fs will use
NFSv2 unless the /etc/fstab entry has the "nfsv3" option
specified.
