fe0d408987 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

83f2409369 Don't print the chipset value; it's not useful.
Now we know what some of the state values are, print the current array
state.

ba2ace5164 Change the queueing model used by the controller to drastically reduce
the time spent at splbio().  We now avoid it unless we are actually
manipulating the command queues themselves.  This doesn't improve
performance noticeably, but should improve concurrency somewhat.

cd4ace0c76 Use the physical block number, not the logical block number, for I/O
operations.  The latter only works where the partion begins at the bottom
of the disk.  Whoops.

d5a51e03e7 This is a driver for the AMI MegaRAID family of controllers. It all of
the AMI PCI controllers using the 8LD firmware interface (40LD firmware
will be supported as soon as I have hardware to test with).

These controllers are rebadged by Dell as the PERC, as well as by HP
and possibly other vendors.
