keep the thread state variable consistent with its real state.
i.e. Don't say it's on the run queue when it isn't.

This manpage should really have only one short description (.Nd);
if anyone could come up with a wording suitable for both conversion
and decoding/encoding functions, that would unbreak the whatis(1)
output for this manpage.

the preformatted files are compressed with the same program
as the source, and if the source files are uncompressed, the
preformatted files are also uncompressed.

o Lock down the ldt_entries array and ldt_free, which points to
the next free slot. As noted in the comments, it's necessary
to special case the initial_thread because %gs is not setup
for it yet. This is ok because that early in the program there
won't be any reentrancy issues anyways.

When in either the mutex or cond queue we notice that the thread
is already on one of the queues, don't just simply abort(). Print
out the thread's identifiers and what queue it was on.

Thus, treat all page faults while in a critical section as fatal rather
than just those that occur with a non-empty spinlocks list. All such page
faults are fatal anyways. Calling trap_fatal() earlier increases the
chances of getting more useful panic messages and a possible DDB prompt.

failt and data access fault install the PTE in question into
the VHPT table. However, a post-increment was missing and we
wrote the raw PTE data into the pagesize/access key field.
This leaves a corrupt VHPT entry.
o While here, remove the explicit cache purge. Insertion into
the translation implicitly purges any overlapping entries.
o Make sure there's a cycle break between the itc and the rfi.
o Whitespace fixes.
a mutex. The only volatile chain operations are insertion and deletion
but since updating an existing PTE also updates the VHPT entry itself,
and we have the VHPT mutex in both other cases, we also lock when we
update an existing PTE even though no chain operation is involved.
Note that we perform the insertion and deletion careful enough that
we don't need to lock traversals. If we need to lock traversals, we
also need to lock from the exception handler, which we can't without
creating a trapframe.
We're now able to withstand a -j8 buildworld. More work is needed to
withstand Murphy fields. In other words: we still have a bogon...
