Logan Gunthorpe 1e2fd202f8 ntb_hw_switchtec: Check for alignment of the buffer in mw_set_trans() ... With Switchtec hardware, the buffer used for a memory window must be aligned to its size (the hardware only replaces the lower bits). In certain circumstances dma_alloc_coherent() will not provide a buffer that adheres to this requirement like when using the CMA and CONFIG_CMA_ALIGNMENT is set lower than the buffer size. When we get an unaligned buffer mw_set_trans() should return an error. We also log an error so we know the cause of the problem.
