[ Upstream commit e02637e97d68a54b1527bc654bf8377eda310226 ]
DMA_VIRT_OPS requires that dma_addr_t is at least as wide as a pointer, which is expressed as a dependency on !64BIT || ARCH_DMA_ADDR_T_64BIT.
For parisc64 this is not true, and if these IB modules are enabled, kconfig warns:
WARNING: unmet direct dependencies detected for DMA_VIRT_OPS Depends on [n]: HAS_DMA [=y] && (!64BIT [=y] || ARCH_DMA_ADDR_T_64BIT) Selected by [m]: - INFINIBAND_RDMAVT [=m] && INFINIBAND [=m] && 64BIT [=y] && PCI [=y] - RDMA_RXE [=m] && INET [=y] && PCI [=y] && INFINIBAND [=m]
Add dependencies to fix this.
