2013-09-02RDMA/ocrdma: Increase STAG array sizeNaresh Gottumukkala
1) Increase STAG Array size. 2) Max inline data size should be set to the same value used during QP creation 3) Set max_sge_rd to zero since we dont support RD transport in our adapters. 4) Max cqes reported in ibv_devinfo should be from QUERY_CONFIG.

2013-09-02RDMA/ocrdma: Dont use PD 0 for userpace CQ DBNaresh Gottumukkala
Create_CQ verb doesn't provide a PD pointer. So, until now we are creating all (both userspace and kernel) CQ DB regions from PD0. This will result in mmapping PD0 to applications. A rogue userspace application can mess things up. Also more serious issues is even the be2net NIC uses PD0. This patch addresses this problem by: 1) Create a PD page for every userspace application when the alloc_ucontext is called. This will be destroyed in dealloc_ucontext. 2) All CQs for that context will use the PD allocated in ucontext. 3) The first create_PD call from application will result in returning the PD address from its ucontext (no new PD will be created). 4) For subsecquent create_pd calls from application, we create new PDs for the application.

2013-09-02RDMA/ocrdma: Fix to work with even a single MSI-X vectorNaresh Gottumukkala
There are cases like SRIOV where can get only one MSI-X vector allocated for RoCE. In that case we need to use the vector for both data plane and control plane. We need to use EQ create version V2.

2012-05-08RDMA/ocrdma: Fix warnings about uninitialized variablesRoland Dreier
First, fix drivers/infiniband/hw/ocrdma/ocrdma_verbs.c: In function 'ocrdma_alloc_pd': drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:371:17: warning: 'dpp_page_addr' may be used uninitialized in this function [-Wuninitialized] drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:337:6: note: 'dpp_page_addr' was declared here which seems that it may border on a bug (the call to ocrdma_del_mmap() might conceivably do bad things if pd->dpp_enabled is not set and dpp_page_addr ends up with just the wrong value). Also take care of: drivers/infiniband/hw/ocrdma/ocrdma_hw.c: In function 'ocrdma_init_hw': drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2587:5: warning: 'status' may be used uninitialized in this function [-Wuninitialized] drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2549:17: note: 'status' was declared here which is only real if num_eq == 0, which should be impossible.
