2015-06-02IB/core cleanup: Add const on args - device->process_madIra Weiny
The process_mad device function declares some parameters as "in". Make those parameters const and adjust the call tree under process_mad in the various drivers accordingly.

2015-05-20IB/core: Add per port immutable struct to ib_deviceIra Weiny
As of commit 5eb620c81ce3 "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.

2015-05-20IB/user_mad: Fix buggy usage of port indexIra Weiny
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.

2015-05-18IB/srp: Add 64-bit LUN supportBart Van Assche
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 9cb78c16f5da ("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).

2015-05-18scsi_transport_srp: Reduce failover timeBart Van Assche
Unlike FC, there is no risk that SCSI devices will be offlined by the SCSI error handler if the SCSI error handler is started while a reconnect attempt is ongoing. Hence report timeout errors as soon as possible if a higher software layer (e.g. multipathd) needs to be informed about a timeout. It is assumed that if both fast_io_fail_tmo < 0 and rport->dev_loss_tmo < 0 that this means that there is no need to report timeouts quickly.
