The implementation of it is missing (see e.g. NetBSD or OpenBSD). Until
someone works on it, comment out the existing code to silence a warning
about 'hostname' being set but unused.

When deallocate_dependencies() is performed,
softdep_journal_freeblocks() already called cancel_allocdirect() which
should have eliminated direct dependencies for all truncated full
blocks. The indirect dependencies are allowed above, since second-
and third-level dependencies are only dealt with by the code which
frees indirect block, which happens after the inode write.

Some of errors were returned to the main function, some others caused a direct
exit via err(3).
The main function is only interested in EXIT_SUCCESS, so in all other cases
replace warn(3) + return err by err(3)
within all of these functions, and is only stored in some to correctly pad
the stack.
This will be needed to build as Thumb-2 as, unlike with ARM instructions,
the msr instruction only takes a register as the input.
This change among other things improve search capabilities over the manpages
allowing fine grain query.
A new build option WITHOUT_MANDOCDB has been added to keep the ancient version
of the database and the tools. The plan is to entirely remove this option before
11.0-RELEASE.

The arm version hasn't been used in ages.
The mips version uses a valid, but pointless check of v1 and has been
unhooked from the build since r276630.

tdsigwakeup() increases the priority of the low-priority threads, to
give them a chance to be terminated timely. Also, kernel allows user
to signal kernel processes. The combined effect is that signalling
idle process bump a priority of the selected delivery thread, which
starts eating CPU.
Check for the delivery thread be an idle thread and do not raise its
priority then.
The signal delivery to the kernel threads must be opt-in feature.
Kernel thread should explicitely declare the ability to handle signals
directed to it. E.g., nfsd threads check for signal as an indication
of exit request.
Most threads do not handle signals at all, and queuing the signal to
them causes odd side-effects. Most innocent consequence is the memory
leak due to queued ksiginfo, which is never deleted from the sigqueue.
Code to prevent even queuing signals to the kernel threads is trivial,
but it requires careful examination of each call to kproc/kthread
creation to decide should the signalling be allowed. The commit is a
stop-gap measure which fixes the immediate case for now.
