ba4371ba78 Revert my previous two changes.
Even though the code seems to be FreeBSD kernel code, it isn't compiled
on FreeBSD. I could have known this, because I was a little amazed that
I couldn't find a prototype of pfopen()/pfclose() somewhere else,
because it isn't marked as static.

Apart from that, removing these functions wouldn't have been harmful
anyway, because there are some other strange things about them (the
implementation isn't consistent with the prototype at the top). Still,
it's better to leave it, because it makes merging code back to older
branches a little harder.

6b2f4a1972 Remove pfopen() and pfclose() entirely.
It turns out I was patching functions that weren't used by pf(4) anyway.
They still seem to use `struct proc *' instead of `struct thread *'.
They weren't listed in pf_cdevsw.

4a0deaef86 Remove unneeded checking for invalid minor numbers from pf(4).
Because it is not possible to access the pf(4) character device through
any other device node as the one in devfs, there is no need to check for
unknown device minor numbers.

97295d8b75 When a statically linked binary is executed (or at least, one without
an interpreter definition in its program header), set the auxiliary
ELF argument AT_BASE to 0 rather than to the address that we would
have mapped the interpreter at if there had been one.

The ELF ABI specifications appear to be ambiguous as to the desired
behavior in this situation, as they define AT_BASE as the base address
of the interpreter, but do not mention what to do if there is none.
On Solaris, AT_BASE will be set to the base address of the static
binary if there is no interpreter, and on Linux, AT_BASE is set to 0.
We go with the Linux semantics as they are of more immediate utility
and allow the early runtime environment to know that the kernel has
not mapped an interpreter, but because AT_PHDR points at the ELF
header for the running binary, it is still possible to retrieve all
required mapping information when the process starts should it be
required.  Either approach would be preferable to our current behavior
of passing a pointer to an unmapped region of user memory as AT_BASE.

fab213569d Instead of killing the 'watchdog' subshell and leaving a sleep for
rcshutdown_timeout (normally 30s) around re-parented to init, make
sure both go away using pkill -P.

While noone normally notices this for the system shutdown, it helps for
cleanly shutting down trusted jails.
Found without a killall in the base system, which in rc.d/jail normally
ensures that all processes of a jail to be stopped will be killed.

69d1bd8670 - Make the keg abstraction more complete. Permit a zone to have multiple
backend kegs so it may source compatible memory from multiple backends.
   This is useful for cases such as NUMA or different layouts for the same
   memory type.
 - Provide a new api for adding new backend kegs to secondary zones.
 - Provide a new flag for adjusting the layout of zones to stagger
   allocations better across cache lines.

d4c94410f6 - Use __XSTRING where I want the define to be expanded. This resulted in
sizeof("MAXCPU") being used to calculate a string length rather than
   something more reasonable such as sizeof("32").  This shouldn't have
   caused any ill effect until we run on machines with 1000000 or more
   cpus.

63e5efcb88 If the parent up/down task was queued then sync with it before returning from
the vap ioctl. This means that the parent interface should hopefully be up
before we return to userland, it does not depend on the parent init succeeding,
just that it was run.

This fixes wpa_supplicant with ndis and USB where the parent interfaces can be
slow to init.

3688ae7441 Fix errors introduced when I rewrote select.
- Restructure selscan() and selrescan() to avoid producing extra selfps
   when we have a fd in multiple sets.  As described below multiple selfps
   may still exist for other reasons.
 - Make selrescan() tolerate multiple selfds for a given descriptor
   set since sockets use two selinfos per fd.  If an event on each selinfo
   fires selrescan() will see the descriptor twice.  This could result in
   select() returning 2x the number of fds actually existing in fd sets.

aaaff3620b Add explicit static DTrace tracing to the callout mechanism, capturing
pointers to the callout handler just before and just after the callout
it invoked.  I attempted to do this in a manner congruent to tracing in
Solaris's callout mechanism, but couldn't quite use the same names due
to convention and syntax differences.

Example DTrace script to generate a distribution graph of callout
execution times:

callout_execute:::callout_start
{
        self->cstart = timestamp;
}

callout_execute:::callout_end
{

        @length = quantize(timestamp - self->cstart);
}

that to make sure that
	make -DKERNFAST buildkernel
remains the same as
	make -DKERNFAST KERNCONF=GENERIC buildkernel
rather than trying to build and configure "1".  I've never seen a
kernel config file named "1," so I think this is a good compromise.
