a78f502d16 Set correct maximum I/O length. We can only handle I/O of up to
max_request_segments * PAGE_SIZE if the I/O is page-aligned; the
largest I/O we can guarantee will work is PAGE_SIZE less than that.
This unbreaks 'diskinfo -t'.

1d758da820 Add a KASSERT to make it obvious when fork_norfproc() is to be called,
and set *procp to NULL in all cases.  Previously, it was not being set
in the ERESTART case.  This is effectively no-op, since its value is
ignored by callers in the error case.

1620fca5f4 Fix scanning after loosing a connection. The firmware assumes that as long
as an association ID is set any scan is supposed to be a background scan.
This implies that the firmware will switch back to the associated channel
after a certain threshold, though, we are not notified about that. We
currently catch this case by a timer which will reset the firmware after
a 'scan timeout', though, upper layers are not notified about that and
will simply hang until manual intervention. Fix this by resetting the
firmware's knowledge about any association on RUN -> ASSOC and
!INIT -> SCAN transitions.

80d6042924 Fixes for monitor mode:
- Do not call iwn_calib_reset() for monitor mode. We do not want to query
  information and do runtime calibration while in monitor mode. Poking the
  firmware with adjustments for calibration results in firmware asserts.
  This could happened on RUN -> RUN transition only.
- Adjust blink rate for monitor mode. It's supposed to not freak out and
  turn off after a while.
- While here, remove one useless assignment of calib.state, it gets
  overwritten later in the function.

fdaa38b44c Do not leak %rdx value in the previous image to the new image after
execve(2). Note that ia32 binaries already handle this properly,
since ia32_setregs() resets td_retval[1], but not exec_setregs().

We still do not conform to the amd64 ABI specification, since %rsp
on the image startup is not aligned to 16 bytes.

e41ab538e4 Use GEOM stripesize field when calculating ashift. This will enable correct
alignment on drives with large sector sizes (e.g. 4 KiB) but the
implementation might need to be revisited if devices with large stripesizes
appear (e.g. if RAID controllers or flash drives start using the field),
probably by introducing a physsectorsize field in GEOM providers.

91e61ea9fc sh: Improve jobs output of pipelines.
If describing the status of a pipeline, write all elements of the pipeline
and show the status of the last process (which would also end up in $?).
Only write one report per job, not one for every process that exits.

To keep some earlier behaviour, if any process started by the shell in a
foreground job terminates because of a signal, write a message about the
signal (at most one message per job, however).

Also, do not write messages about signals in the wait builtin in
non-interactive shells. Only true foreground jobs now write such messages
(for example, "Terminated").

225ceb18e8 Add a "kernel" log function, based on e_log.c, which is useful for
implementing accurate logarithms in different bases.  This is based
on an approach bde coded up years ago.

This function should always be inlined; it will be used in only a few
places, and rudimentary tests show a 40% performance improvement in
implementations of log2() and log10() on amd64.

The kernel takes a reduced argument x and returns the same polynomial
approximation as e_log.c, but omitting the low-order term. The low-order
term is much larger than the rest of the approximation, so the caller of
the kernel function can scale it to the appropriate base in extra precision
and obtain a much more accurate answer than by using log(x)/log(b).

506e81b852 sh: Avoid marking a job as done before it is fully created.
In r208489, I added code to reap zombies when forking new processes, to
limit the amount of zombies. However, this can lead to marking a job as done
or stopped if it consists of multiple processes and the first process ends
very quickly. Fix this by only checking for zombies before forking the first
process of a job and not marking any jobs without processes as done or
stopped.
