2015-11-09scsi: use host wide tags by defaultChristoph Hellwig
This patch changes the !blk-mq path to the same defaults as the blk-mq I/O path by always enabling block tagging, and always using host wide tags. We've had blk-mq available for a few releases so bugs with this mode should have been ironed out, and this ensures we get better coverage of over tagging setup over different configs.

kmalloc() can return NULL and without checking we were dereferencing it. Moreover if kmalloc succeeds but the function fails in other parts then we were returning the error code but we missed freeing lcb_context. While at it fixed one related checkpatch warning.

2015-10-27Fix kmalloc overflow in LPFC driver at large core countIan Mitchell
This patch allows the LPFC to start up without a fatal kernel bug based on an exceeded KMALLOC_MAX_SIZE and a too large NR_CPU-based maskbits field. The bug was based on the number of CPU cores in a system. Using the get_cpu_mask() function declared in kernel/cpu.c allows the driver to load on the community kernel 4.2 RC1.

2015-10-27lpfc: in sli3 use configured sg_seg_cnt for sg_tablesizeBodo Stroesser
Currently the module parameter lpfc_sg_seg_count does not have effect for sli3 devices. In lpfc_sli_driver_resource_setup(), which is used for sli3, the code writes the configured sg_seg_cnt into lpfc_template.sg_tablesize. But lpfc_template is the template used for sli4 only. Thus the value should correctly be written to lpfc_template_s3->sg_tablesize. This patch is for kernel 4.1-rc5, but is tested with lpfc 10.2.405.26 only.

2015-06-05lpfc: The lpfc driver does not issue RFF_ID and RFT_ID in the correct sequenceJames Smart
The order (it's a shall, but hard to dictate after the fact) is given in FC-SCM - kind of. SCM indicates what shall be implemented, lists it as (a), (b), (c), but actually doesn't say it has to be in that order. The only hard requirement, called out in FCP-4, is that you must register your FC-4 Type (via RFT_ID) before registering FC-4 Type Features (via RFF_ID), which makes sense. We obviously violated this and there were some switches (or newer fw in them) that enforced it. The other rule of thumbs are: register your data with the switch first, then register for SCRs, then do queries about the fabric, with the SCRs telling you of changes post the queries.
