headers. Device documentation often times give offsets relative to the
start of the entire VSEC, not just the post-header data area, so this
change makes it easier to correlate offsets.
Modules from ports/pkg are commonly installed to /boot/modules rather than to
the same directory the kernel resides in. Look there if a module is not found
next to the kernel.

autofs was introduced with FreeBSD 10.1 and is the supported method for
automounting filesystems. As of r296194 the amd man page claimed that it
is deprecated. Remove it from base now; the sysutils/am-utils port is
still available if necessary.

It does extremely useful things like execute sendmail and spew dubiously
accurate factoids.
From the feedback, it seems like it is an essential utility in a modern unix
and not at all a useless bikeshed. How do those Linux people live without it?
Reverts r358561.
With powerd_flags="-N", this makes powerd(8) exclude "nice" time when
computing the CPU utilization. This makes it possible to prevent
CPU-intensive "background" processes from spinning up the CPU.
Note that only *userland* CPU usage belonging to "nice" processes is
excluded; we do not track whether time spent in the kernel is on behalf
of nice or non-nice processes, so kernel-intensive nice processes can
still result in the CPU being sped up.

This is the result of splitting r358153 in two, in order to avoid a build
system bug and being able to merge the change to previous releases..
Document better this file, updating the URL to the IANA registry and closely
match the official services.
For system ports (0 to 1023) we now try to follow the registry closely, noting
some historical differences where applicable.
As a side effect: drop references to unofficial Kerberos IV which was EOL'ed
on Oct 2006[1]. While it is conceivable some people may still use it in some
very old FreeBSD machines that can't be replaced easily, the use of it is
considered a security risk. Also drop the unofficial netatalk, which we
supported long ago in the kernel but was dropped long ago.
Leave for now smtps, even though it conflicts with IANA's submissions.
The change should have very little visibility, if any, but should be a
step closer to the current IANA database.

Give up the battle to keep extra files in $MACHINE/compile to keep the file in
the tree. Instead, create CDIR (usually ../compile) if it doesn't exist when
we're using a default build location (eg, not using -d). If it does, we do
nothing. This only affects people that do old-school builds, but it's bit me a
dozen times since last summer so time to fix the bug.
This change reflects the ability to change machine_arch in a config file. This
is useful for including one config in another and changing the machine_arch
in the second one.
Currently, you can have multiple machine directives if they are otherwise
identical. Relax this so that only the machinename part is the same. This allows
one to change the machine arch in a different config file you've included easily.
Currently, the size of the swap device is unconditionally reported using
blocks, even if -h has been used.
- While here, switch to CONVERT_BLOCKS() instead of CONVERT() which will
avoid overflowing size counters (in human readable form see: r196244)
- Update the column headers to reflect that a size is being reported instead
of the block size units being used

This patch adds a new netbe_peek_recvlen() function to the net
backend API. The new function allows the virtio-net receive code
to know in advance how many virtio descriptors chains will be
needed to receive the next packet. As a result, the implementation
of the virtio-net mergeable rx buffers feature becomes efficient,
so that we can enable it also with the tap(4) backend. For the
tap(4) backend, a bounce buffer is introduced to implement the
peeck_recvlen() callback, which implies an additional packet copy
on the receive datapath. In the future, it should be possible to
remove the bounce buffer (and so the additional copy), by
obtaining the length of the next packet from kevent data.

For the User ports (1024 - 49151) we try to keep some sensible balance only

to strike a balance between complexity and usefulness.

ACPI Control Method Batteries have a _BIF and/or _BIX object which
provide static properties of the battery. FreeBSD acpi_cmbat module
supported _BIF object only, which was deprecated as of ACPI 4.0.
_BIX is an extended version of _BIF defined in ACPI 4.0 or later.
As of writing, _BIX has two revisions. One is in ACPI 4.0 (rev.0) and
another is in ACPI 6.0 (rev.1). It seems that hardware vendors still
stick to _BIF only or _BIX rev.0 + _BIF for the maximum compatibility.
Microsoft requires _BIX rev.0 for Windows machines, so there are some
laptop machines with _BIX rev.0 only. In this case, FreeBSD does not
recognize the battery information.
After this change, the acpi_cmbat module gets battery information from
_BIX or _BIF object and internally uses _BIX rev.1 data structure as
the primary information store in the kernel. ACPIIO_BATT_GET_BI[FX]
returns an acpi_bi[fx] structure built by using information obtained
from a _BIF or a _BIX object found on the system. The revision number
field can be used to check which field is available. The acpiconf(8)
utility will show additional information if _BIX is available.
Although ABIs of ACPIIO_BATT_* were changed, the existing APIs for
userland utilities are not changed and the backward-compatible ABIs
are provided. This means that older versions of acpiconf(8) can also
work with the new kernel. The (union acpi_battery_ioctl_arg) was
padded to 256 byte long to avoid another ABI change in the future.
A _BIX object with its revision number >1 will be treated as
compatible with the rev.1 _BIX format.

"Oops" - ln(1) is fine and dandy, but when you're using DESTDIR...it's not-
the path will almost certainly be invalid once the root you've just
installed to is relocated, perhaps to /.
Switch to install(1) using `-l rs` to calculate the relative symlink between
the two, which should work just fine in all cases.

services: Add PROFInet and EtherCAT.
Both are admitedly very niche features and no known users exist currently.
I am doing a further review/update of the services file (see D23621) and
both of these are not likely to be considered.
This patch cleans up the API between the net frontends (e1000,
virtio-net) and the net backends (tap and netmap).
We move the virtio-net header stripping/prepending to the
virtio-net code, where this functionality belongs.
In this way, the netbe_send() and netbe_recv() signatures
can have const struct iov * rather than struct iov *.

Rip out vfork() and the rest of the references to it. fork is heavier, but
it's unclear that the difference will be all that obvious.
