Add a new ib_cq_init_attr structure which contains the previous cqe (minimum number of CQ entries) and comp_vector (completion vector) in addition to a new flags field. All vendors' create_cq callbacks are changed in order to work with the new API. This commit does not change any functionality.

A reorganisation of the PD allocation and deallocation in commit 9ba1377d ("RDMA/ocrdma: Move PD resource management to driver.") introduced a double free on pd, as detected by static analysis by smatch: drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:682 ocrdma_alloc_pd() error: double free of 'pd'^ The original call to ocrdma_mbx_dealloc_pd() (which does not kfree pd) was replaced with a call to _ocrdma_dealloc_pd() (which does kfree pd). The kfree following this call causes the double free, so just remove it to fix the problem. Fixes: 9ba1377d ("RDMA/ocrdma: Move PD resource management to driver.")

This code causes a static checker warning: drivers/infiniband/hw/usnic/usnic_uiom.c:476 usnic_uiom_alloc_pd() warn: passing zero to 'PTR_ERR' This code isn't buggy, but iommu_domain_alloc() doesn't return an error pointer so we can simplify the error handling and silence the static checker warning.

Registering an event handler is done for a device. This device may have one RoCE port (no SA cap) and one InfiniBand port (has SA cap). Therefore, warning from the event handler about a specific port that doesn't have SA cap is correct but pollutes the kernel log without a need.

As of commit 5eb620c8 "IB/core: Add helpers for uncached GID and P_Key searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in the ib_device. The per port core capability flags to be added later are also immutable data to be stored in the ib_device object. In preparation for this create a structure for per port immutable data and place the pkey and gid table lengths within this structure. "get_port_immutable" is added as a mandatory device function to allow the drivers to fill in this data.

The addition of the rdma_cap_ib_mad is technically broken in ib_umad_remove_one because the loop "i" value is not a port value. This bug resulted in the ib_umad failing to properly remove its resources when the core capability functions were converted to bit fields. NOTE: e17371d73908 did not result in broken behavior on its own. It was only an issue when the implementation of rdma_cap_ib_mad was changed. Pass the port value to rdma_cap_ib_mad.

The SCSI standard defines 64-bit values for LUNs. Large arrays employing large or hierarchical LUN numbers become more and more common. So update the SRP initiator to use 64-bit LUN numbers. See also Hannes Reinecke, commit 9cb78c16 ("scsi: use 64-bit LUNs"), June 2014. The largest LUN number that has been tested is 0xd2003fff00000000. Checked the following structure sizes with gdb: * sizeof(struct srp_cmd) = 48 * sizeof(struct srp_tsk_mgmt) = 48 * sizeof(struct srp_aer_req) = 36 The ibmvscsi changes have been compile tested only (on a PPC system).
