(reposting) how to get DMA'able memory within 4GB on 64-bit machine

I posted this sometime back but I guess probably it got lost. 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

how to get DMA'able memory within 4GB on 64-bit machine

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
