This patch fixes 2 issues in the fast completion path: 1) Possible double completions / double dma_unmap_sg() calls due to lack of atomicity in the check and subsequent dereference of the upper layer callback function. Fixed with cmpxchg before unmap and callback. 2) Regression in unaligned IO constraining workaround for p420m devices. Fixed by checking if IO is unaligned and using proper semaphore if so.
Sam, what is this patch against? It doesn't apply to -rc6 and it doesn't apply to for-3.15/drivers (the latter would be preferred/required). It also seems to have line break issues.
