While strictly speaking this is not correct since some fields are pointers,
it makes no difference on all supported archs and we already rely on it doing
the right thing in other places.
No functional changes.
"export foo=bar" form instead of "foo=bar; export foo" since the
former allows the shell to catch variable names that are not valid
shell identifiers. This will cause /bin/sh to exit with an error
(which gets mailed to the at user) and it will not run the script.

In some code that is shared between the ixl(4) and ixlv(4) drivers,
a macro hard-coded a register offset that was not valid on ixlv devices.
Fix this by having each driver define a variable that contains the correct
offset.

The "systat -ifstat" command was using a u_int to store byte counters.
With a 10Gbps or faster interface, this overflows within the default
5 second refresh period. Switch to using a uint64_t across the board,
which matches the size used for all counters as of r263102.

This will only take effect if PORTSDIR is not set, as previously supported.
Use .if exists(), for four specific possibilities relative to .CURDIR:
., .., ../.., and ../../.. The fourth possibility is primarily in case
ports ever grows a third level. If none of these paths exist, fall back to
the old default of /usr/ports.
This removes the need to set PORTSDIR explicitly (or via wrapper script) if
one is running out of a ports tree that is not in /usr/ports, but in a
home directory.

Use adequately sized buffer for error(s) (512 -> PATH_MAX + 512).
Fix the following style(9) nits while here:
- distfetch.c uses PATH_MAX while distextract.c uses MAXPATHLEN;
standardize on one (PATH_MAX)
- Move $FreeBSD$ from comment to __FBSDID()
- Sort included headers (alphabetically, sys/* at top)
- Add missing header includes (e.g., <stdlib.h> for getenv(3),
calloc(3)/malloc(3)/free(3), and atoi(3); <string.h> for strdup(3),
strrchr(3), strsep(3), and strcmp(3); <ctype.h> for isspace(3); and
<unistd.h> for chdir(2), etc.)
- Remove rogue newline at end of distfetch.c
- Don't declare variables in if-, while-, or other statement
NB: To prevent masking of prior declarations atop function
- Perform stack alignment for variable declarations
- Add missing function prototype for count_files() in distextract.c
- Break out single-line multivariable-declarations
NB: Aligning similarly-named variables with one-char difference(s)
NB: Minimizes diffs and makes future diffs more clear
- Use err(3) family of functions (requires s/int err;/int retval;/g)

Add support for the missing POSIX-2001 %U and %W features: the
existing FreeBSD strptime code recognizes both directives and
validates that the week number lies in the permitted range,
but then simply discards the value.
Initial support for the feature was written by Paul Green.
David Carlier added the initial handling of tm_wday/tm_yday.
Major credit goes to Andrey Chernov for detecting much of the
brokenness, and rewriting/cleaning most of the code, making it
much more robust.
Tested independently with the strptime test from the GNU C
library.

that the tty is dequeued from 'tty_list' only the first time.
The panic below was seen when a revoke(2) was issued on an nmdm device.
In this case there was also a thread that was blocked on a read(2) on the
device. The revoke(2) woke up the blocked thread which would typically
return an error to userspace. In this case the reader also held the last
reference on the file descriptor so fdrop() ended up calling tty_rel_free()
via ttydev_close().
tty_rel_free() then tried to dequeue 'tp' again which led to the panic.

This seems to allow us to pass a universe with either clang or gcc
after r272244 (and r272260) and probably makes it easier to untabgle
these chained #includes in the future.
if_var.h has the expected on and if_var.h include ifq.h and thus we get
duplicates. It seems only one cavium ethernet file actually includes ifq.h
directly which might be another cleanup to be done but need to test first.
There's a bug in the AR7240 PCIe hardware where a correct BAR will end
up having the device disappear.
It turns out that for the device address it should be all 0's.
However, this meant that the PCI probe code would try writing 0xffffffff
in to see how big the window was, read back 0x0, and think the window
was 32 bits. It then ended up calculating a resource size of 0 bytes,
failed to find anything via an rman call, and this would fail to attach.
I have quite absolutely no idea how in the various planes of existence
this particular bit of code and how it worked with the PCI bus code
ever worked. But, well, it did.
Tested:
* Atheros AP93 - AR7240 + AR9280 reference board
It was doing incorrect things with masks. This was fixed in the
AR71xx codebase but it wasn't yet fixed in the AR724x code.
This ended up having config space reads return larger/incorrect values
in some situations.
Tested:
* AR7240
TODO:
* test ar7241, AR7242, and AR934x.
of the FreeBSD release builds.
This adds a make(1) environment variable requirement,
WITH_VMIMAGES, which triggers the virtual machine image
targets when not defined to an empty value.
Relevant user-driven variables include:
o VMFORMATS: The virtual machine image formats to create.
Valid formats are provided by running 'mkimg --formats'
o VMSIZE: The size of the resulting virtual machine
image. Typical compression is roughly 140Mb, regardless
of the target size (10GB, 15GB, 20GB, 40GB sizes have been
tested with the same result).
o VMBASE: The prefix of the virtual machine disk images.
The VMBASE make(1) environment variable is suffixed with
each format in VMFORMATS for each individual disk image, as
well as '.img' for the source UFS filesystem passed to
mkimg(1).
This also includes a new script, mk-vmimage.sh, based on how
the VM images for 10.0-RELEASE, 9.3-RELEASE, and 10.1-RELEASE
were created (mk-vmimage.sh in ^/user/gjb/thermite/).
With the order in which the stages need to occur, as well as
sanity-checking error cases, it makes much more sense to
execute a shell script called from make(1), using env(1) to
set specific parameters for the target image than it does to
do this in make(1) directly.
