Dave Jiang 4f302642b7 dmaengine: idxd: fix interrupt completion after unmasking ... The current implementation may miss completions after we unmask the interrupt. In order to make sure we process all competions, we need to: 1. Do an MMIO read from the device as a barrier to ensure that all PCI writes for completions have arrived. 2. Check for any additional completions that we missed.
