    iwlwifi: load firmware in chunks · 83f84d7b
    Johannes Berg 提交于
    Instead of allocating one big chunk of DMA-coherent
    memory for the firmware and keeping it around, only
    vmalloc() the firmware and copy it into a single
    page of DMA-coherent memory for the upload.
    
    The advantage is that we don't need DMA memory for
    the firmware image that is stored while the driver
    is operating, we only need it while uploading.
    
    This will make it easier for the driver to work if
    the system has fragmented memory.
