It did "halt". ;^)
pci_dma_supported() is supposed to be called first by all drivers wishing
to use Dynamic DMA interfaces. I'm thinking a test in pci_dma_supported()
macro could oops nicely if hppa_dma_ops isn't set.
For "devices" which aren't claimed (eg CCIO), we need to make sure
the HVERS/SVERS values are make available to the device maintainer.
I'll poke dhd offline in this case.
