applied after:
- merging with "ide-tape: remove pipeline-specific code from idetape_setup"
- cleaning up __idetape_discard_read_pipeline() (since patch #3 was dropped)
- cleaning up idetape_empty_write_pipeline() (since patch #4 was dropped)

changed this to export '1' to user-space
(which has always meant that pipeline-mode is disabled)
