Make previous change in interpreter entry point calculation dependant on
a 'mips' define. XXX

Just a temporary patch to get things going again for Linux ELF binaries,
needs to be solved properly.
Cast the printf("%ld", sizeof) in eoniphdr to long.
This fix a -Wall error on non alpha systems
Removed a load of [cb]dev_decl() lines that are provided by sys/conf.h
Removed duplicate LKM option.
restrict the FSTATE_STAR prohibition (and panic) to the i386 only.  Cloning
devices actually do make sense on indirect-config busses, because you
might be able to have more than one of the busses!  In addition, they're
useful because they don't require unit numbers to be wired down, so you
could e.g. have vga* at indirect? and vga* at direct?, and have the first
one found be unit number zero.  Finally, devices which can divine their
own ports numbers, etc., actually should be cloning, even if you know you'll
only have one bus that they can live on.
Update and clarifications (addresses PR#2933).
cast pointers to long, not int, and fix the resulting printf format goof.
Provide a routine so that ISA/EISA bridges can set up a callback so
that their child busses can be attached after the PCI bus
autoconfiguration for their parent bus is done.

This works because:
	(1) there can be at most one ISA/EISA bridge per PCI bus, and
	(2) any ISA/EISA bridges must be attached to primary PCI
	    busses (i.e. bus zero).

That boils down to: there can only be one of these outstanding
at a time, it is cleared when configuring PCI bus 0 before any
subdevices have been found, and it is run after all subdevices
of PCI bus 0 have been found.

This (or something like it) is needed because there are some (legacy)
PCI devices which can show up as ISA/EISA devices as well (the prime
example of which are VGA controllers).  If you attach ISA from a
PCI-ISA/EISA bridge, and the bridge is seen before the video board is,
the board can show up as an ISA device, and that can (bogusly)
complicate the PCI device's attach code, or make the PCI device not be
properly attached at all.

This could be done with machine-dependent code, but as more ports
add support for PCI (and PCI-ISA/EISA bridges) more will need it.
The i386 port could (perhaps should) be converted to use it as well.
Drop LPT_NPORTS to 4 from 8.  Some lpt units require only 4 I/O ports
(e.g. from 0x3bc to 0x3bf, for example).  Others may require more,
but until there's some special handling for them, 4 should be returned
so that on systems with I/O port accounting, the unit at 0x3bf can be
properly mapped, etc.  (OK'd by mycroft.)
fix two problems with shutdown hook code:
(1) after removing a shutdown hook (in shutdownhook_disestablish()),
    free it.  We created it, we have to free it.  Without this,
    shutdownhook_disestablish() leaks memory.
(2) in doshutdownhooks(), before running each hook, remove it from the
    shutdown hook list.  This makes sure that every hook is tried once
    (because doshutdownhooks() is called from before rebooting, and
    a fault in a shutdown hook will cause doshutdownhooks() to be called
    again), but prevents the hooks from potentially being run infinitely
    (as used to be possible, in the above-mentioned situation).
sync up with pk's commit to the sparc port:
>One control block per target is insufficient if you have a full complement
>of targets attached and access those simultaneously (like in a ccd(4) array).
>We (now) allocate (somewhat arbitrarily) three per target.
