Implement a MIPS FDT PIC decode routine to use when no PIC has been
configured, which assumes a cascade back to the nexus bus (e.g.,
the on-board CP0 interrupt management parts on the MIPS). If the
soc bus in a MIPS DTS file is declared as "mips4k,cp0"-compatible,
then this will be enabled. This is sufficient to allow IRQs to be
configured on BERI.

Provided a bus_space implementation for FDT, modelled on
bus_space_generic, but with a local version of the map address
routine that does a P->V translation, as is the case with NLM's
similar routine for XLP. It's not clear to me that this is the
right solution -- possibly this belongs in simplebus -- however,
it is sufficient to get the DE4 LED driver working.

In a sign of weakness, replicate the MIPS bus_space_generic.c to
produce a new FDT version, which will perform necessary address
space translation for bus_space -- the solution used in NLM's MIPS
FDT support, but possibly not quite the right thing. This is
inconsistent with regular I/O via the nexus and the generic
bus_space, which instead perform translation via pmap_mapdev()
when a resource is activated. However, it will work while I
attempt to identify what the right way to reconcile possible
approaches.
(Another approach might be to make simplebus use Nexus's activate
routine instead of a generic one?)

Add code so that the BERI boot process can ask the kernel linker for

This implementation is not functionaly complete comparing to Windows,

So, now in6_setscope reads zone IDs for interface-local, link-local and

Previously CTL would leave individual LUNs enabled in the target
driver, whether or not the port as a whole was enabled. It would
also leave the wildcard LUN enabled indefinitely.
This change means that CTL will enable and disable any active LUNs,
as well as the wildcard LUN, when enabling and disabling a port.
Also, fix a bug that could crop up due to an uninitialized CCB
type.
ctl.c: Before calling ctl_frontend_online(), run through
the LUN list and enable all active LUNs.
After calling ctl_frontend_offline(), run through
the LUN list and disble all active LUNs.
scsi_ctl.c: Before bringing a port online, allocate the
wildcard peripheral for that bus. And after taking
a port offline, invalidate the wildcard peripheral
for that bus.

in devfs if a particular race condition is hit in the device pager
code.
This was a side effect of change 227530 which changed the device
pager interface to call a new destructor routine for the cdev.
That destructor routine, old_dev_pager_dtor(), takes a VM object
handle.
The object handle is cast to a struct cdev *, and passed into
dev_rel().
That works in most cases, except the case in cdev_pager_allocate()
where there is a race condition between two threads allocating an
object backed by the same device. The loser of the race
deallocates its object at the end of the function.
The problem is that before inserting the object into the
dev_pager_object_list, the object's handle is changed from the
struct cdev pointer to the object's own address. This is to avoid
conflicts with the winner of the race, which already inserted an
object in the list with a handle that is a pointer to the same cdev
structure.
The object is then passed to vm_object_deallocate(), and eventually
makes its way down to old_dev_pager_dtor(). That function passes
the handle pointer (which is actually a VM object, not a struct
cdev as usual) into dev_rel(). dev_rel() decrements the reference
count in the assumed struct cdev (which happens to be 0), and
that triggers the assertion in dev_rel() that the reference count
is greater than or equal to 0.
The fix is to add a cdev pointer to the VM object, and use that
pointer when calling the cdev_pg_dtor() routine.
vm_object.h: Add a struct cdev pointer to the VM object
structure.
device_pager.c: In cdev_pager_allocate(), populate the new cdev
pointer.
In dev_pager_dealloc(), use the new cdev pointer
when calling the object's cdev_pg_dtor() routine.
