worker_loop() uses schedule_timeout() without setting state to STATE_(UN)INTERRUPTIBLE. As it is called in cycle without checking of pending signals, use schedule_timeout_uninterruptible().

Hi all, this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs with a separate new dma_alloc_pages API, which is available on all platforms. In addition to cleaning up the convoluted code path, this ensures that other drivers that have asked for better support for non-coherent DMA to pages with incurring bounce buffering over can finally be properly supported.
