    Based on the earlier work by Tejun Heo.
    
    * Move setting IDE_TFLAG_LBA48 taskfile flag from do_rw_taskfile()
      function to the callers.
    
    * Add IDE_TFLAG_FLAGGED taskfile flag for flagged taskfiles coming
      from ide_taskfile_ioctl().  Check it instead of ->tf_out_flags.all.
    
    * Add IDE_TFLAG_OUT_DATA taskfile flag to indicate the need to load
      IDE data register in ide_tf_load().
    
    * Add IDE_TFLAG_OUT_* taskfile flags to indicate the need to load
      particular IDE taskfile registers in ide_tf_load().
    
    * Update do_rw_taskfile() and ide_tf_load() users to set respective
      IDE_TFLAG_OUT_* taksfile flags.
    
    * Add task_dma_ok() helper.
    
    * Use IDE_TFLAG_FLAGGED taskfile flag to select HIHI mask in ide_tf_load().
    
    * Use do_rw_taskfile() in flagged_taskfile().
    
    * Remove no longer needed 'tf_out_flags' field from ide_task_t.
    
    There should be no functionality changes caused by this patch.
