dmaengine: ioatdma: adding shutdown support

2015-09-21T15:40:05Z

The ioatdma needs to be queisced and block all additional op submission during reboots. When NET_DMA was used, this caused issue as ops were still being sent to ioatdma during reboots even though PCI BME has been turned off. Even though NET_DMA has been deprecated, we need to prevent similar situations. The shutdown handler should address that. Signed-off-by: Dave Jiang Signed-off-by: Vinod Koul
