Mikulas Patocka 5a71f14a9b dma-debug: change allocation mode from GFP_NOWAIT to GFP_ATIOMIC ... [ Upstream commit 84bc4f1dbbbb5f8aa68706a96711dccb28b518e5 ] We observed the error "cacheline tracking ENOMEM, dma-debug disabled" during a light system load (copying some files). The reason for this error is that the dma_active_cacheline radix tree uses GFP_NOWAIT allocation - so it can't access the emergency memory reserves and it fails as soon as anybody reaches the watermark. This patch changes GFP_NOWAIT to GFP_ATOMIC, so that it can access the emergency memory reserves.
