net: remove mm.h inclusion from netdevice.h 2012-01-31T06:25:55+00:00 Alexey Dobriyan adobriyan@gmail.com 2011-06-16T11:01:34+00:00 b26010288d78150c305f8342004478b8500cd88d Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

ENGR00170901-2 IMX/UART : add a wait queue for DMA RX in SMP 2012-01-09T13:12:31+00:00 Huang Shijie b32955@freescale.com 2011-12-21T08:34:08+00:00 86df8e08c87ae4b41b03b275b18463b4b6297840 The DMA RX thread may run on another CPU, while the application runs on one CPU. The application will close the uart when it finishes the required reading. But the DMA RX thread maybe still running in this situation.
