aeb6641f8e lpfc: fix misleading indentation 
gcc-6 complains about the indentation of the lpfc_destroy_vport_work_array()
call in lpfc_online(), which clearly doesn't look right:

drivers/scsi/lpfc/lpfc_init.c: In function 'lpfc_online':
drivers/scsi/lpfc/lpfc_init.c:2880:3: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]
   lpfc_destroy_vport_work_array(phba, vports);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/lpfc/lpfc_init.c:2863:2: note: ...this 'if' clause, but it is not
  if (vports != NULL)
  ^~

Looking at the patch that introduced this code, it's clear that the
behavior is correct and the indentation is wrong.

This fixes the indentation and adds curly braces around the previous
if() block for clarity, as that is most likely what caused the code
to be misindented in the first place.

c0365c0692 Fix kmalloc overflow in LPFC driver at large core count 
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.

Below is the kernel bug reproduced:

on a UV2 machine with 6144 cores. With the fix, the LPFC module loads
with no unwanted effects on the system.

5f406fae01 lpfc: in sli3 use configured sg_seg_cnt for sg_tablesize 
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.

8b0dff1416 lpfc: Add support for using block multi-queue 
With blk-mq support in the mid-layer, lpfc can do IO steering based
on the information in the request tag.  This patch allows lpfc to use
blk-mq if enabled. If not enabled, we fall back into the emulex-internal
affinity mappings.

This feature can be turned on via CONFIG_SCSI_MQ_DEFAULT or passing
scsi_mod.use_blk_mq=Y as a parameter to the kernel.

be6bb94100 lpfc: Fix premature release of rpi bit in bitmask 
Currently, the driver plays off the fact that older sli4 adapters have a
different rpi access pattern that allowed for the rpi reference to be
released earlier in the teardown sequence, allowing the driver to recycle
the rpi value sooner. Newer sli4 adapters have a different access pattern that
requires us to wait for a later mailbox completion. This changes the put
call location on the newer sli4 adapters.

Symptoms of the error are "0110 ELS" and the "0372 iotag" errors.

ea4142f6b1 lpfc: Fix host reset escalation killing all IOs. 
Fix host reset escalation killing all IOs.

SLI-3 adapters will use a new host template. The template differs
from SLI-4 adapters in that it does not have an eh_host_reset_handler.

Lpfc has traditionally never had a host_reset. The host reset
handler was added when we ran into a stuck hardware condition on a
SLI-4 adapter. The host_reset will reset and reinit the pci function,
clearing the hardware condition.

Unfortunately, the host reset handler uses attach/detach code paths,
which makes scsi_add_host() and scsi_remove_host() calls. Meaning, a
host_reset will completely remove the scsi_host from the system. As a
new call to scsi_add_host() is made, the shost# changes, which results
in completely new scsi_devices and device names. All the older scsi
devices on the old shost# are now orphaned and unrecoverable.

We realize we need to re-implement the host_reset_handler so the scsi_host
stays registered across the host_reset, but that will be a rather
lengthy effort. In the short term, we had an immediate need to restore
the SLI-3 devices to their working behavior, with the easiest path being
to remove their host_reset handler.
