Conrad Meyer 0d0f264099 ioat(4): Use memory completion rather than device register ... The CHANSTS register is a split 64-bit register on CBDMA units before hardware v3.3. If a torn read happens during ioat_process_events(), software cannot know when to stop completing descriptors correctly. So, just use the device-pushed main memory channel status instead. Remove the ioat_get_active() seatbelt as well. It does nothing if the completion address is valid. Sponsored by: Dell EMC Isilon		2016-10-28 23:53:37 +00:00
