iwlwifi: load firmware in chunks
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. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
