Christoph Hellwig 66d7780f18 dma-mapping: check pfn validity in dma_common_{mmap,get_sgtable} ... Check that the pfn returned from arch_dma_coherent_to_pfn refers to a valid page and reject the mmap / get_sgtable requests otherwise. Based on the arm implementation of the mmap and get_sgtable methods. Signed-off-by: Christoph Hellwig <hch@lst.de> Tested-by: Vignesh Raghavendra <vigneshr@ti.com>		2019-07-24 17:28:54 +02:00
