As it was pointed out by Alan Cox, that no longer serves its purpose with
the modern UMA allocator compared to the old one used in 4.x days.
The removal of sysctl eliminates max_proc_mmap type overflow leading to
the broken mmap(2) seen with large amount of physical memory on arches
with factually unbound KVA space (such as amd64). It was found that
slightly less than 256GB of physmem was enough to trigger the overflow.

ctfconvert will corrupt object files that are compiled with -g, if it is
not run with -g itself.
To fix it, remove -g from CFLAGS in lib/librt/Makefile. If you need to
compile this library with debug info, use DEBUG_FLAGS=-g instead, which
will work correctly, even when using WITH_CTF.

different processes that happen to use the same user address in the
separate processes will now be treated as distinct futexes rather than the
same futex. We can now honor shared futexes properly by mapping them to a
PROCESS_SHARED umtx_key. Private futexes use THREAD_SHARED umtx_key

While I'm here remove dc_reset() in DC_ISR_BUS_ERR case. Device is
fully reinitialized again in dc_init_locked().
The old version had a race between the time that the old file was
cp'ed to acct.0 and the time that 'sa -s' was run that prevented
the commands that occurred in the meantime from being backed up.
It's also arguable that the old version was inefficient in using
cp which can be a problem on a space-constrained system.
This version avoids both problems, albeit it's considerably more
complicated. The advantage of putting the log rotation in the rc.d
script is that it can handle the _enable and _file questions without
having to do gymnastics to discover either value in the periodic script.
As a side effect of reviewing the rc.d script I cleaned it up a bit.
file's last accessed, modified, and changed times:
TMPFS_NODE_ACCESSED and TMPFS_NODE_CHANGED should be set unconditionally
in tmpfs_remove() without regard to the number of hard links to the file.
Otherwise, after the last directory entry for a file has been removed, a
process that still has the file open could read stale values for the last
accessed and changed times with fstat(2).
Similarly, tmpfs_close() should update the time-related fields even if all
directory entries for a file have been removed. In this case, the effect
is that the time-related fields will have values that are later than
expected. They will correspond to the time at which fstat(2) is called.

A full featured groff is required during buildworld, so build it always

vgrind(1) is tightly coupled to a roff processor and will not be

* packet durations for TDMA slot decisions;
* RTS/CTS protection durations;
* updating the duration field in the 802.11 frame header
This way invalid durations will generate a warning, prompting for it to be
fixed.
