    SubjectRe: PCI DMA to small buffers on cache-incoherent arch
    From

    Wait a second, forget all of this cache alignment crap. If we can
    avoid drivers seeing it, we should by all means necessary.

    We should just tell people to use PCI pools and be done with it. That
    way all the complexity about buffer alignment and all this other
    crapola lives strictly inside of the PCI pool code.
