1fe6c4ee54 Add SCSI passthrough support to CISS. This allows devices like tape drives
that are on a CISS bus to be exported up to CAM and made available as normal
devices.  This will typically add one or two buses to CAM, which will be
numbered starting at 32 to allow room for CISS proxy buses.  Also, the CISS
firmware usually hides disk devices, but these can also be exposed as 'pass'
devices if you set the hw.ciss.expose_hidden_physical tunable.

3c6b835326 There's no need to call ciss_report_request in the passthru ioctl
routine since the error will be reported back to the user buffer.
This will quiet down the bootverbose case when using an ACU which
does brute force discovery of the physical and logical devices.

c61314601b Add support for the HP Modular Smart Array 20 & 500 storage arrays.
Logical volumes on these devices show up as LUNs behind another
controller (also known as proxy controller).  In order to issue
firmware commands for a volume on a proxy controller, they must be
targeted at the address of the proxy controller it is attached to,
not the Host/PCI controller.

A proxy controller is defined as a device listed in the INQUIRY
PHYSICAL LUNS command who's L2 and L3 SCSI addresses are zero.  The
corresponding address returned defines which "bus" the controller
lives on and we use this to create a virtual CAM bus.

A logical volume's addresses first byte defines the logical drive
number.  The second byte defines the bus that it is attached to
which corresponds to the BUS of the proxy controller's found or the
Host/PCI controller.

Change event notification to be handled in its own kernel thread.
This is needed since some events may require the driver to sleep
on some operations and this cannot be done during interrupt context.
With this change, it is now possible to create and destroy logical
volumes from FreeBSD, but it requires a native application to
construct the proper firmware commands which is not publicly
available.

Special thanks to John Cagle @ HP for providing remote access to
all the hardware and beating on the storage engineers at HP to
answer my questions.

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.
