Re: [PATCH] libata: Add pata_dma option so users can disable pata_dma as they can with old-ide

Allow

	libata.pata_dma=0

to disable DMA (default is 1)

SATA is unaffected as disabling DMA for SATA makes no sense at all.

Alan,

Should we really be piling up like this on global boot/module options
rather than run-time flags on individual channels/devices ?

I can imagine systems with internal notebook drives that want dma=1,
plus Cardbus CF devices that require dma=0.

With a single global flag, how does one do that?

Cheers
