If the smmu is enabled, the length of sg obtained from
__iommu_map_sg_attrs is not 4kB. When the IOVA is set with the sg
dma address, the IOVA will not be page continuous.
In order to fix this issue, the IOVA should be calculated based on
the sg length.

This patch-set introduces three patches to fix about the memory
related issues.
Wei Hu (Xavier) (3):
RDMA/hns: Fix the issue of IOVA not page continuous in hip08
RDMA/hns: Get rid of virt_to_page and vmap calls after
dma_alloc_coherent
RDMA/hns: Get rid of page operation after
current code, there are incorrect usage as below:
dma_alloc_coherent + virt_to_page + vmap. This patch fixes it to
get rid of virt_to_page and vmap calls.

The hardware vendors need to generate RoCEv1 or RoCEv2
packet according to the sgid type configured.
Besides, update the gid table size for hip08 RoCE
