Conrad Meyer faefad9c12 ioat: Handle channel-fatal HW errors safely ... Certain invalid operations trigger hardware error conditions. Error conditions that only halt one channel can be detected and recovered by resetting the channel. Error conditions that halt the whole device are generally not recoverable. Add a sysctl to inject channel-fatal HW errors, 'dev.ioat.<N>.force_hw_error=1'. When a halt due to a channel error is detected, ioat(4) blocks new operations from being queued on the channel, completes any outstanding operations with an error status, and resets the channel before allowing new operations to be queued again. Update ioat.4 to document error recovery; document blockfill introduced in r290021 while we are here; document ioat_put_dmaengine() added in r289907; document DMA_NO_WAIT added in r289982.
