firewall logging on and off when at elevated securelevel(8). It would
be nice to be able to only lock these at securelevel >= 3, like rules
are, but there is no such functionality at present. I don't see reason
to be adding features to securelevel(8) with MAC being merged into 5.0.

MFC after: 1 week
pmap_zero_page() and pmap_zero_page_area() were modified to accept
a struct vm_page * instead of a physical address, vm_page_zero_fill()
and vm_page_zero_fill_area() have served no purpose.
a pointer to a symbol is given and we have to find the containing symbol
table. We do this by bounds checking. For some strange reason (ie I
haven't found the root cause) the first test succeeded for said symbol,
implying that the symbol came from the .dynsym table. In reality however
the symbol actually resided in the .symtab table. Needless to say that
all that was returned was junk.
The upper bounds check was: (symptr - baseptr) < symtab_size
This has been rewritten to: symptr < (baseptr + symtab_size)
As a side-effect, slightly more optimal (and still correct :-) code can
be generated on ia64.
some circumstances when we get a select collision, we can end up with
cases where we do not clear some sip->si_thread on the way out, leading to
page faults in selwakeup(). This should solve the problem where postfix
can crash the kernel during select collisions.

This state is to allow some experimentation and not YET used..
The theory is that a thread that is about to sleep is placed on the sleep
queue and then discovers it should suspend, and is placed on suspend queue.
(these are separate queues and it can be on both). It will not become runnable
until it has been removed from BOTH queues. i.e. a wakeup event
has occured AND the process has been unsuspended. If it were not on the sleep
queue when suspended, then the (possibly only) wakeup event might arrive and
not find any process to wake up. this would result in the thread
sleeping 'forever' when the suspension is lifted. This state will
transition to one of TDS_SLP or TDS_SUSPENDED, depending upon which
constraint is lifted first.
o Move mode_t details from <sys/types.h> into <sys/_types.h>.
o Add primitives for sharing the mode_t and off_t typedefs.
o Add typedefs mode_t, off_t, and size_t to <sys/mman.h>.

These types are unlikely to ever become very MD. They include:
clockid_t, ct_rune_t, fflags_t, intrmask_t, mbstate_t, off_t, pid_t,
rune_t, socklen_t, timer_t, wchar_t, and wint_t.
While moving them, make a few adjustments (submitted by bde):
o __ct_rune_t needs to be precisely `int', not necessarily __int32_t,
since the arg type of the ctype functions is int.
o __rune_t, __wchar_t and __wint_t inherit this via a typedef of
__ct_rune_t.
o Some minor wording changes in the comment blocks for ct_rune_t and
mbstate_t.

Attempt to determine what function of AUX_OUT is: "True line level
out", "Headphone out", or "4-Channel out" and frig OSS mixer label
accordingly.
Addresses problem raised by Randy Bush on -multimedia of not being
able to hear audio on ich2 m/b which was eventually found to be
because the mixer monitor value was 0. On this h/w the label
"monitor" should now be presented as the marginally more intuitive
"ogain".
