Curiously, the in-kernel routines always use the design voltage to
convert from mA to mW, but acpiconf in userland uses the current
voltage. As a result, this can report a different mW rate than
acpiconf.

If RLIM_INFINITY == -1ULL (such as on macOS) the min() call will result
in a value of less than 1 being returned. This causes nftw() to fail
with EINVAL.
While touching this file also fix includes to work on Linux/macOS and don't
declare snprintf since it may have different attributes in the system
headers there.

With lld-generated binaries the first PT_LOAD will usually be a read-only
segment unless you pass --no-rosegment. For those binaries the textsize is
determined by the next PT_LOAD. To allow both LLD and bfd 2.17 binaries to
be parsed correctly use the end of the last PT_LOAD that is marked as
executable instead.
I noticed that the value was wrong while adding some debug prints for some rtld
changes for CHERI binaries. `obj->textsize` only seems to be used by PPC so the
effect is untested. However, the value before was definitely wrong and the new
result matches the phdrs.

AVAHI to the list. This fixes the textproc/docproj build
seemingly following FLAVORS being added.
Specifically, the problem with the dependency chain here is:
- textproc/docproj depends on print/cups, which sets AVAHI=on
by default;
- net/avahi-app depends on devel/gobject-introspection, which
requires python3+;
- graphics/netpbm depends on graphics/mesa-libs, which can
only be built with python2.7;
- textproc/docproj depends on a number of graphics ports for
font rendering, etc.

taskqgroup_detach() would remove the task even if it was running or
enqueued, which could lead to panics (see D17404). With this change,
taskqgroup_detach() drains the task and sets a new flag which prevents the
task from being scheduled again.
I've added grouptask_block() and grouptask_unblock() to allow control
over the flag from other locations as well.

The previous iteration of try_include attempted to be 'friendly' and error()
out if we hit an error that wasn't ENOENT. This was semi-OK, but fragile as
it relied on pattern matching the error message.
Move the responsibility for handling failure to the caller. Following
a common lua pattern, we'll return the return value of the underlying
require() on success, or false and an error message.

of the widget had to be 10 wider than the text. Recent updates to dialog
have changed the requirement to be at least 12 wider than the hline text
else the hline text is not rendered at the bottom of the widget.

The provided example jail configs do not work for multiple interfaces.
Multiple interfaces need to be specified as a comma separated list or

on amd64 in FreeBSD 12, with appropriate instructions for loading the
necessary netgraph ether module (ng_ether) since it is neither built-

on-write faults. On a page fault, when we call vm_fault_prefault(), it
probes the pmap and the shadow chain of vm objects to see if there are
opportunities to create read and/or execute-only mappings to neighoring
pages. For example, in the case of hard faults, such effort typically pays
off, that is, mappings are created that eliminate future soft page faults.
However, in the the case of soft, copy-on-write faults, the effort very
rarely pays off. (See the review for some specific data.)
