Hi List,

Is there a way for a driver to ask kernel to
give DMA'able memory within 4GB ? I read about
pci_alloc_consistent(). But I could not find out
whether that guarantees the DMA'able memory to be
within 4GB or not. Is there any other kernel routine
that I should call from Driver to get such a memory ?
