Hi Marcello,

I posted this small one-liner to Alan Cox (and to the lkml) in August but 
it doesn't seem to have gotten into the mainline yet (I think it is in -ac).

The issue is that PCI drivers which uses 64bit DMA masks (in order to do 
DAC) is making unnecessary use of the DMA zone memory (the <16Meg region 
on i386) when doing pci_alloc_consitent().

Hope this gets into the next -rc or .21-pre

Regards,
