 - remove internal queueing
 - fix hardware datastructures
 - remove odd ioctls
 - remove useless forward prototypes
 - give types like ACB useful names
 - give variable useful names, especially follow kernel conventions,
   e.g. a struct pci_dev is usually named pdev
 - kill ->proc_info method
 - use normal comment style even for comments not fitting into the
   kernel-doc item above.  kill useless separator comments without
   text
 - convert arcmsr_show_firmware_info to useful one value per
   file attributes.  best follow the schemes used in aacraid or
   lpfc
 - convert arcmsr_show_driver_state to useful one value per
   file attributes.
 - remove never called release method in the host template
 - audit whether setting unchecked_isa_dma to false really makes
   sense (I strongly doubt it)
 - remove shutdown notifier, add pci_driver ->shutdown method instead
 - remove CameCase PCI Ids.  The vendor Id should go into pci_ids.h,
   the device ids either removed or spelled the normal linux way
 - arcmsr_do_interrupt should stop walking the global host list
   and use the private data passed to request_irq
 - the global host list should go away completely
 - arcmsr_bios_param looks like duplicating the generic CAM version?
 - locking needs to be redone.  If the driver really needs more than
   one per-host lock we'll want a very good explanation
 - arcmsr_device_probe needs to be rewritten to do goto-based
   error unwinding.
 - msi should be a module options if at all, but defintitly not
   a config options
 - arcmsr_scsi_host_template_init should go away.  the host template
   must be initialized statically with no run-time writes to it
 - the hardware documentation should be split out of arcmsr.h
   into a separate file (btw, thanks a lot to areca to provide such
   detailed hardware informations, it's just the wrong format..)
 - remove the SCSISTAT_* defines, and use the generic ones from
   <scsi/scsi.h> instead.  Dito for various other SAM defines.
 - the driver has just two files and should go directly into
   drivers/scsi instead of a subdirectory
