8bd452c648 Create an MI Ether3 driver. It's derived from the arm26 driver, which uses 
my MI SEEQ 8005 driver, which is based on the arm32 ea driver.

2714607c72 Add podulebus_shift_tag, which generates a bus_space_tag_t with a specified 
address shift (stride).  This is necessary because many podules have standard
chips with odd address-bus wiring to allow for using LDM for
bus_space_*_multi_*().

86d6442c28 Move machine-dependent podulebus headers to <machine/podulebus_machdep.h>. 
<dev/podulebus/podulebus.h> is the canonical file to include, and includes
<machine/podulebus_machdep.h>.
<arch/${MACHINE}/poudulebus/podulebus.h> remains for backward compatibility.

61e80eef9b As Richard Earnshaw pointed out, bus_space_copy_1() and bus_space_copy_2() 
had the wrong names and did the wrong things.  Both are now fixed.

c40daf0aed change uvm_winsize to uvm_winshift so that we can avoid division 
by a non-constant value.

5c98fe3fec Gratuitous change of signature for podulebus_irq_establish(). It now takes 
an opaque podulebus_intr_handle_t, which can be found in podulebus_attach_args.
It's actually the slot number, but don't tell anyone.

949f93d279 If uvm_fault() returns an error, pass it on to the pcb_onfault handler 
if there is one.  They already arrange to return it to their callers.

bfc2063e69 Create an ARM2-specific undefined-instruction handler which deals with the 
undef/SWI bug and handles emulating SWP.

Untested bacuse my ARM2 machine isn't currently set up.

ac3bc537bd eliminate the KERN_* error codes in favor of the traditional E* codes. 
the mapping is:

KERN_SUCCESS			0
KERN_INVALID_ADDRESS		EFAULT
KERN_PROTECTION_FAILURE		EACCES
KERN_NO_SPACE			ENOMEM
KERN_INVALID_ARGUMENT		EINVAL
KERN_FAILURE			various, mostly turn into KASSERTs
KERN_RESOURCE_SHORTAGE		ENOMEM
KERN_NOT_RECEIVER		<unused>
KERN_NO_ACCESS			<unused>
KERN_PAGES_LOCKED		<unused>

c3c5158d00 Change the value of tf_pc in undefined-instruction handlers on arm32. It now 
always points to the undefined instruction in question.  It's up to the
handler to advance it to the next instruction if it wants execution to
continue there.  This is how things have always worked on arm26.

b1475781a2 Make arm26 implementation of DDB slightly less gratuitously different from the 
ARM one.  Also update for recent undefined-instruction handler changes.

ce5529eabf Change undefined instruction handler to use a linked list for each 
co-processor.  This is necessary so we can have several handlers for
CP0 (used as a catch-all for non-CP instructions).

Handlers are now removed using remove_coproc_handler(), rather than by calling
install_coproc_handler() with a NULL handler.

Because install_coproc_handler() can now allocate memory, there's a version
for use at boot time that doesn't.

f6c36838ae Use the same undefined-instuction handler on both arm26 and arm32. The handler 
is derived mostly from the arm32 version, but with a check for an obscure ARM2
bug thrown in.

arm26 fpu and cpu drivers use the new interface for catching undefined
instructions.

96b16f75a6 Hack to allow arm26 to have its own "cpu" device. This device should really
