    * Don't set write-only ide_task_t.hobRegister[6] and ide_task_t.hobRegister[7]
      in idedisk_set_max_address_ext().
    
    * Add struct ide_taskfile and use it in ide_task_t instead of tfRegister[]
      and hobRegister[].
    
    * Remove no longer needed IDE_CONTROL_OFFSET_HOB define.
    
    * Add #ifndef/#endif __KERNEL__ around definitions of {task,hob}_struct_t.
    
    While at it:
    
    * Use ATA_LBA define for LBA bit (0x40) as suggested by Tejun Heo.
    
    v2:
    * Add missing newlines. (Noticed by Sergei)
    
    * Use ~ATA_LBA instead of 0xBF. (Noticed by Sergei)
    
    * Use unnamed unions for error/feature and status/command.
      (Suggested by Sergei).
    
    There should be no functionality changes caused by this patch.
