Fine but please update status of following host drivers that were
marked as "stable" prematurely by commit e3389cb first:

PATA_PDC_OLD: needs to be marked as EXPERIMENTAL (or just BROKEN)
- known reliability problems with UDMA

PATA_ALI: EXPERIMENTAL
- ATAPI DMA is still broken

PATA_CMD64X: EXPERIMENTAL
- potential data corruption issues remains unfixed for CMD64[3,6]

PATA_SIS: EXPERIMENTAL
- missing MWDMA support on newer controllers

They are all old & known problems and not present in
[ "old", "deprecated", "legacy" ] counterparts.
