Make functions only used in one file local.
Remove lots of dead code. Most surprising is the function
cxgb4_iscsi_init which is defined but never called!
Compile tested only

drivers/scsi/cxgbi/cxgb4i/cxgb4i.c:1423:	cxgb4_iscsi_init(lldi->ports[0], tagmask, pgsz_factor);

You are changing to static or removing entirely functions exported for use 
by the iSCSI and RDMA drivers.  The function you mention, cxgb4_iscsi_init, 
  is used in the cxgb4i driver in the scsi tree and this change breaks it.
