3cf53e8550 printf(1): Clarify that \OOO produces a byte, different %b escape sequences.
Octal escape sequences are expanded to bytes, not characters, and multiple
are required for a multibyte character.

The valid escape sequences in %b strings are slightly different from the
escape sequences in the format string.

09538b1020 Several improvements to HPET driver:
- Add special check for case when time expires before being programmed.
This fixes interrupt loss and respectively timer death on attempt to
program very short interval. Increase minimal supported period to more
realistic value.
 - Add support for hint.hpet.X.allowed_irqs tunable, allowing manually
specify which interrupts driver allowed to use. Unluckily, many BIOSes
program wrong allowed interrupts mask, so driver tries to stay on safe
side by not using unshareable ISA IRQs. This option gives control over
this limitation, allowing more per-CPU timers to be provided, when FSB
interrupts are not supported. Value of this tunable is bitmask.
 - Do not use regular interrupts on virtual machines. QEMU and VirtualBox
do not support them properly, that may cause problems. Stay safe by default.
Same time both QEMU and VirtualBox work fine in legacy_route mode.
VirtualBox also works fine if manually specify allowed ISA IRQs with above.

b3c63ff614 libedit: Try to map <Delete> to ed-delete-next-char.
This adds a new "arrow" key "delete" corresponding to the kD termcap value.
It only works if that is a sequence such as "\033[3~"; if it is "\177", the
em-delete-prev-char or ed-delete-prev-char from the single-character
mappings remains. It turns out that most terminals (xterm and alikes,
syscons in xterm mode) produce "\033[3~" by default so <Delete> has the
expected effect.

This also means that things need to be considerably misconfigured for
<Backspace> to perform a <Delete> action.

21f9b7b28a Allowed unionfs to use whiteout not supporting file system as
upper layer. Until now, unionfs prevents to use that kind of
file system as upper layer. This time, I changed to allow
that kind of file system as upper layer. By this change, you
can use whiteout not supporting file system (e.g., especially
for tmpfs) as upper layer. It's very useful for combination of
tmpfs as upper layer and read only file system as lower layer.

By difinition, without whiteout support from the file system
backing the upper layer, there is no way that delete and rename
operations on lower layer objects can be done.  EOPNOTSUPP is
returned for this kind of operations as generated by VOP_WHITEOUT()
along with any others which would make modifica tions to the
lower layer, such as chmod(1).

This change is suggested by ed.

ef3b7ba04f struct device: widen type of flags and order fields to u_int
Also change int -> u_int for order parameter in device_add_child_ordered.
There should not be any ABI change as struct device is private to subr_bus.c
and the API change should be compatible.

To do: change int -> u_int for order parameter of bus_add_child method
and its implementations.  The change should also be API compatible, but
is a bit more churn.

fe5d61a4cf sh: Do not use locale for determining if something is a name.
This makes it impossible to use locale-specific characters in variable
names.

Names containing locale-specific characters make scripts only work with the
correct locale setting. Also, they did not even work in many practical cases
because multibyte character sets such as utf-8 are not supported.

This also avoids weirdness if LC_CTYPE is changed in the middle of a script.

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.
