47e5204ee3 sh: Remove special support for background simple commands.

54b16435b7 sh: Add do-nothing -h option.
POSIX requires a -h option to sh and set, to locate and remember utilities
invoked by functions as they are defined. Given that this
locate-and-remember process is optional elsewhere, it seems safe enough to
make this option do nothing.

POSIX does not specify a long name for this option. Follow ksh in calling it
"trackall".

8f0e65c915 Add DTrace support to the new NFS client. This is essentially
cloned from the old NFS client, plus additions for NFSv4. A
review of this code is in progress, however it was felt by the
reviewer that it could go in now, before code slush. Any changes
required by the review can be committed as bug fixes later.

279a233d0c libprocstat: For MAP_PRIVATE, do not consider the file open for writing.
If a file is mapped with with MAP_PRIVATE, no write permission is required
and changes do not end up in the file. Therefore, tools like fuser and fstat
should not show the file as open for writing.

The protection as displayed by procstat -v still includes write in this
case, and shows 'C' for copy-on-write.

1696274411 fuser: Fix skipping "SIG" on signal names (-s).
The code did  !strncasecmp(str, "sig", 4)  which is not useful.

Also change "sig" to "SIG" matching the uppercase signal names as of
r218285. This has little effect because fuser does not enable locale.

a2f43b6155 - As with stray vector interrupts limit the reporting of stray level
interrupts. Bringup on additional machine models repeatedly reveals
  firmware that enables interrupts behind our back, causing the console
  to be flooded otherwise.
- As with the regular interrupt counters using uint16_t instead of
  u_long for counting the stray vector interrupts should be more than
  sufficient.
- Cache the interrupt vector in intr_stray_vector().

o  Set TP using inline assembly to avoid dead code elimination.
o  Eliminate _tcb.

Merge from r161840:
Stylize: avoid using a global register variable.

Merge from r157461:
Simplify _get_curthread() and _tcb_ctor because libc and rtld now
already allocate thread pointer space in tls block for initial thread.

Merge from r177853:
Replace function _umtx_op with _umtx_op_err, the later function directly
returns errno, because errno can be mucked by user's signal handler and
most of pthread api heavily depends on errno to be correct, this change
should improve stability of the thread library.

cfb739b854 rc.subr: Eliminate about 100 forks from the boot sequence.
With the current sh, placing eval in a command substitution always results
in a fork(), even if it is the only command and only executes a single
simple command. Therefore, avoid it where it can be avoided easily.

Side effect: values starting with a hyphen and all whitespace are preserved.

52dcd04ba3 gre(4) was using a field in the softc to detect possible recursion.
On MP systems this is not a usable solution anymore and could easily
lead to false positives triggering enough logging that even  using
the console was no longer usable (multiple parallel ping -f can do).

Switch to the suggested solution of using mbuf tags to carry per
packet state between gre_output() invocations.  Contrary to the
proposed solution modelled after gif(4) only allocate one mbuf tag
per packet rather than per packet and per gre_output() pass through.

As the sysctl to control the possible valid (gre in gre) nestings does
no sanity checks, make sure to always allocate space in the mbuf tag
for at least one, and at most 255 possible gre interfaces to detect
loops in addition to the counter.

0b96c05a7a After we get a good power signal, always wait about 10ms before
proceeding.

On boot, some laptops with certain cards in them sometimes fail on
boot, but if the card is inserted after boot it works.  Experiments
show that small delays here makes things more reliable.  It is
believed that some combinations need a little more time before the
power on the card is really stable enough to be reliable once the
power is stable in the bridge.

5df88f46bb Teach the compiler how to shift TSC value efficiently. As noted in r220631,
some times compiler inserts redundant instructions to preserve unused upper
32 bits even when it is casted to a 32-bit value.  Unfortunately, it seems
the problem becomes more serious when it is shifted, especially on amd64.

maintain the databases maintained by utmpx, namely last, users, who,
wtmpcvt, ac, lastlogin and utxrm.

The tool w is not in this list, because it has some other functionality

183c8af32e Don't create a device_t object or parse current resources (via _CRS) for
ACPI Device() objects that do not have any device IDs available via the
_HID or _CID methods.  Without a device ID a device driver cannot attach
to the device anyway.  Namespace objects that are devices but not of
type ACPI_TYPE_DEVICE are not affected.

A few BIOSes have also attached a _CRS method to a PCI device to
allocate resources that are not managed via a BAR.  With the previous
code those resources are allocated from acpi0 directly which can interfere
with the new PCI-PCI bridge driver (since the PCI device in question may
be behind a bridge and its resources should be allocated from that
bridge's windows instead).  The resources were also orphaned and
and would end up associated with some other random device whose device_t
reused the pointer of the original ACPI-enumerated device (after it was
free'd by the ACPI PCI bus driver) in devinfo output which was confusing.
If we want to handle _CRS on PCI devices we can adjust the ACPI PCI bus
driver to do that in the future and associate the resources with the
proper device object respecting PCI-PCI bridges, etc.

Note that with this change the ACPI PCI bus driver no longer has to
delete ACPI-enumerated device_t devices that mirror PCI devices since
they should in general not exist.  There are rare cases when a BIOS
will give a PCI device a _HID (e.g. I've seen a PCI-ISA bridge given
a _HID for a system resource device).  In that case we leave both the
ACPI and PCI-enumerated device_t objects around just as in the previous
code.

1c2ed38455 - Use a dedicated task to handle deferred transmits from the if_transmit
method instead of reusing the existing per-queue interrupt task.
  Reusing the per-queue interrupt task could result in both an interrupt
  thread and the taskqueue thread trying to handle received packets on a
  single queue resulting in out-of-order packet processing.
- Don't define igb_start() at all on 8.0 and where if_transmit is used.
  Replace last remaining call to igb_start() with a loop to kick off
  transmit on each queue instead.
- Call ether_ifdetach() earlier in igb_detach().
- Drain tasks and free taskqueues during igb_detach().

c9afaa6389 sh: Add case statement fallthrough (with ';&' instead of ';;').
Replacing ;; with the new control operator ;& will cause the next list to be
executed as well without checking its pattern, continuing until a list ends
with ;; or until the end of the case statement. This is like omitting
"break" in a C "switch" statement.

The sequence ;& was formerly invalid.

ba2a822490 In HAST we use two sockets - one for only sending the data and one for
only receiving the data. In r220271 the unused directions were
disabled using shutdown(2).

Unfortunately, this broke automatic receive buffer sizing, which
currently works only for connections in ETASBLISHED state. It was a
root cause of the issue reported by users, when connection between
primary and secondary could get stuck.

Disable the code introduced in r220271 until the issue with automatic
buffer sizing is not resolved.
