modifications to libproc to support fetching the CTF info for a given file.
With this change, dtrace(1) is able to resolve type info for function and
USDT probe arguments, and function return values. In particular, the args[n]
syntax should now work for referencing arguments of userland probes,
provided that the requisite CTF info is available.
The uctf tests pass if the test programs are compiled with CTF info. The
current infrastructure around the DTrace test suite doesn't support this
yet.

cylinder, head and track numbers. Return ~0U for these values when
mkimg wasn't given both -T and -H (i.e. no geometry) or the cylinder
would be larger than the provided maximum.
Use mkimgs_chs() for the EBR, MBR and PC98 schemes to fill in the
appropriate fields. Make sure to use a "rounded" size so that the
partition is always a multiple of the track size. We reserved the
room for it in the metadata callback so that's a valid thing to
do.
Bump the mkimg version number.
While doing that again: have mkimg.o depend on the Makefile so that
a version change triggers a rebuild as needed.
Remove previously added kmem methods in favour of defines which
allow diff minimisation between upstream code base.
Rebalance ARC free target to be vm_pageout_wakeup_thresh by default
which eliminates issue where ARC gets minimised instead of balancing

further eliminate code differences.
Add additional DTRACE probe to aid monitoring of ARC behaviour.

including an alignment. Previously binutils would only allow instructions
in the form "vld1.64 {d0, d1}, [r0, :128]" where the final comma should
not be there, instead the above instruction should be

This change duplicates the alignment code from within the function to
handle this case.

Add new functions to manipulate these mode & state, instead of calling
kbdd_ioctl() everyhere.
This fixes at least two bugs:
1. The state of the Scroll Lock LED and the state of scroll mode
could be out-of-sync. For instance, if one enables scroll mode on
window #1 and switches to window #2, the LED would remain on, but
the window wouldn't be in scroll mode.
Similarily, when switching between a console and an X.Org
session, the LED states could be inconsistent with the real
state.
2. When exiting from an X.Org session, the user could be unable to
type anything. The workaround was to switch to another console
window and come back.

Initial commit to include virtual machine images as part
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.
r272236:
Use VMBASE in place of a hard-coded filename in the CLEANFILES
list.
r272262:
Remove a 'set -x' that snuck in during testing.
r272264:
release/Makefile:
Connect the virtual machine image build to the release
target if WITH_VMIMAGES is set to a non-empty value.

Add commented entries for tuning the release build if the
WITH_VMIMAGES make(1) environment variable is set to
a non-empty value.

r272272:
Remove comments left in accidentally while testing, so the
VM /etc/fstab is actually created.
r272277:
Remove the UFS label from the root filesystem since it is added
by mkimg(1) as a gpt label, consistent with the fstab(5) entry.
r272279:
Comment cleanup in panic() message when mkimg(1) does not support
the requested disk image format.
r272376:
Separate release/scripts/mk-vmimage.sh to machine-specific
scripts, making it possible to mimic the functionality for
non-x86 targets.
Move echo output if MAKEFLAGS is empty outside of usage().
Remove TARGET/TARGET_ARCH evaluation.
r272380:
Avoid using env(1) to set values passed to mk-vmimage.sh,
and instead pass the values as arguments to the script,
making it easier to run this by hand, without 'make release'.
Add usage_vm_base() and usage_vm_image() usage helpers.
r272381:
After evaluating WITH_VMIMAGES is non-empty, ensure
the mk-vmimage.sh script exists before running it.
r272392:
Add WITH_COMPRESSED_VMIMAGES variable, which when set enables
xz(1) compression of the virtual machine images.
This is intentionally separate to allow more fine-grained
tuning over which images are compressed, especially in cases
where compressing 20GB sparse images can take hours.
r272412:
Document the new 'vm-image' target, and associated release.conf
variables.
r272413:
Remove two stray comments added during the initial iterations
of testing, no longer needed.
