Hi Jeff,

Attached please find the patch against libata-2.6 for your review.

Changes:
  #1. ata_scsi_rw_xlat():  
    Fix  incorrect SCSI to ATA translation for 16 bytes SCSI Read/Write commands. 
   (Already submitted in the previous patch. Merged with change #2 and resubmitted again.)

  #2. Fix ata_scsi_verify_xlat():
    Fix incorrect tf->hob_lbax translation.

Albert
