      [libata sata_sil] Re-fix mod15write bug · 48c1a573
      Jeff Garzik authored
      Certain early SATA drives have problems with write requests whose
      length satisfy the equation "sectors % 15 == 1", on the SiI 3112.
      Other drives, and other SiI controllers, are not affected.
      
      The fix for this problem is to avoid such requests, in one of three
      ways, for the affect drive+controller combos:
      1) Limit all writes to 15 sectors
      2) Use block layer features to avoid creating requests whose
         length satisfies the above equation.
      3) When a request satisfies the above equation, split the request
         into two writes, neither of which satisfies the equation.
      
      I chose fix #1, the most simple to implement.  After discussion with
      Silicon Image and others regarding the impact of this fix, I have
      decided to remain with fix #1, and will not be implementing a
      "better fix".  This means that the affected SATA drives will see
      decreased performance, but set of affected drives is small and will
      never grow larger.
      
      Further, the complexity of implementing solution #2 or
      solution #3 is rather large.
      
      When implementing lba48 'large request' support, I unintentionally
      broke the fix for these affected drives.  Kudos to Ricky Beam for
      noticing this.
      
      This change restores the fix, by adding a flag ATA_DFLAG_LOCK_SECTORS
      to indicate that the max_sectors value set by the low-level driver
      should never be changed.
