* (the combined receive and send queues) so that they would be aligned
* on their combined size. That alignment guaranteed that they would
* never cross the 4GB boundary (Tavor work queues are on the order of
* MBs at maximum). Now we are able to relax this alignment constraint
* by ensuring that the IB address assigned to the queue memory (as a
* result of the tavor_mr_register() call) is offset from zero.
* Previously, we had wanted to use the ddi_dma_mem_alloc() routine to
* guarantee the alignment, but when attempting to use IOMMU bypass
* mode we found that we were not allowed to specify any alignment that
* was more restrictive than the system page size. So we avoided this
* constraint by passing two alignment values, one for the memory
* allocation itself and the other for the DMA handle (for later bind).
* This used to cause more memory than necessary to be allocated (in
* order to guarantee the more restrictive alignment contraint). But
* be guaranteeing the zero-based IB virtual address for the queue, we
* are able to conserve this memory.
*
* Note: If SRQ is not user-mappable, then it may come from either
* kernel system memory or from HCA-attached local DDR memory.
*
* Note2: We align this queue on a pagesize boundary. This is required
* to make sure that all the resulting IB addresses will start at 0, for
* a zero-based queue. By making sure we are aligned on at least a
* page, any offset we use into our queue will be the same as when we
* perform tavor_srq_modify() operations later.
