[PATCH] I2O: Adaptec specific SG_IO access, firmware access through sysfs and 2400A workaround

Browse Source 
Changes:
 - Provide SG_IO access to BLOCK and EXECUTIVE class on Adaptec
   controllers
 - Use PRIVATE messages in SCSI-OSM because on some controllers normal
   SCSI class commands like READ or READ CAPACITY cause errors
 - Use new DMA and SG list creation function
 - Added workaround to limit sectors per request for Adaptec 2400A
   controllers
