a257bf905e [SCSI] lpfc 8.3.1: misc fixes/changes
8.3.1 Fixes/Changes :

- Fix incorrect byte-swapping on word 4 of IOCB (data length) which
  caused LUNs to not be discovered on big-endian (e.g. PPC)

- Remove a bad cast of MBslimaddr which loses the __iomem (sparse)

- Make lpfc_debugfs_mask_disc_trc static (sparse)

- Correct misspelled word BlockGuard in lpfc_logmsg.h comment

- Replaced repeated code segment for canceling IOCBs from a list with
  a function call, lpfc_sli_cancel_iocbs().

- Increased HBQ buffers to support 40KB SSC sequences.

- Added sysfs interface to update speed and topology parameter without
  link bounce.

- Fixed bug with sysfs fc_host WWNs not being updated after changing
  the WWNs.

- Check if the active mailbox is NULL in the beginning of the mailbox
  timeout handler - fixes panic in the mailbox timeout handler while
  running IO stress test

- Fixed system panic in lpfc_pci_remove_one() due to ndlp indirect
  reference to phba through vport

- Removed de-reference of scsi device after call to scsi_done() to fix
  panic in scsi completion path while accessing scsi device after
  scsi_done is called.

- Fixed "Nodelist not empty" message when unloading the driver after
  target reboot test

- Added LP2105 HBA model description

- Added code to print all 16 words of unrecognized ASYNC events

- Fixed memory leak in vport create + delete loop

- Added support for handling dual error bit from HBA

- Fixed a driver NULL pointer dereference in lpfc_sli_process_sol_iocb

- Fixed a discovery bug with FC switch reboot in lpfc_setup_disc_node

- Take NULL termintator into account when calculating available buffer space

2344b5b685 Fix lpfc_parse_bg_err()'s use of do_div()
Fix lpfc_parse_bg_err()'s use of do_div().  It should be passing a 64-bit
variable as the first parameter.  However, since it's only using a 32-bit
variable, it doesn't need to use do_div() at all, but can instead use the
division operator.

This deals with the following warnings:

    CC      drivers/scsi/lpfc/lpfc_scsi.o
  drivers/scsi/lpfc/lpfc_scsi.c: In function 'lpfc_parse_bg_err':

5b75da2fa2 [SCSI] lpfc 8.3.0 : Add active interrupt test for enabling MSI/MSI-X/INTx
Per the recent discussions at the Linux Plumbers Conference, when
enabling MSI or MSI-X, generate a test interrupt to verify the
interrupt routing is working properly.  If the test interrupt fails,
fall back to MSI first, and if that fails as well, to INTx.  If the
interrupt test fails with INTx, log an error and fail the PCI probe.

Also changed the use of spin_(lock|unlock) to the _irq(save|restore)
variants in the interrupt handlers because with multi-message MSI-X,
both interrupt handlers can now run in parallel.

eaf15d5b56 [SCSI] lpfc 8.3.0 : Fix several minor issues
- Avoid polling HBA Error Attention when HBA's PCI channel is offline
  due to PCI EEH

- Fix handling of RSCN with non-zero event qualifiers

- Remove unnecessary sleeps during HBA initialization which slow down
  driver load

- Fix internal and external loopback on FCoE HBAs

- Fix incorrect decrement of cmd_pending count in lpfc_queuecomand
  error path

- Fix reporting of port busy events to management application

- Rename lpfc_adjust_queue_depth() to lpfc_rampdown_queue_depth() for
  consistency with its partner lpfc_rampup_queue_depth()

- Delete redundant lpfc_cmd->start_time = jiffies assignment in
  lpfc_queuecommand()

- Fix handling for ELS, mailbox and heartbeat time outs in the worker
  thread by removing unnecessary checking of the work_port_events
  flags.

- Fix NULL pointer dereference in lpfc_prep_els_iocb

- In lpfc_device_recov_npr_node(), move clearing of NLP_NPR_2B_DISC
  flag after call to lpfc_cancel_retry_delay_tmo() to keep
  targets-in-discovery count correct

- Remove lpfc_probe_one()'s call to scsi_scan_host() which could cause
  concurrent SCSI scans to step on each other

- Fix lock up on rmmod with vports defined by having
  lpfc_pci_remove_one() invoke fc_vport_terminate() to remove all the
  vports before invoking fc_remove_host() for the physical port

- Fix echotest failure when NPIV is enabled

  template to make the vport disable attribute visible

- Set the vport state to DISABLE on create if the disable flag is
  true

- Call lpfc_alloc_sysfs_attr() for vports so that statistical data
  collection works on them

- Support setting a vport's symbolic name via sysfs by writing to
  /sys/class/fc_vport/vportX/symbolic_name

- Fix create vport fails when link is down or in loop mode.  Should be
  able to be create vports any time NPIV is enabled

915caaaf62 [SCSI] lpfc 8.2.7 : Change device reset behavior
Prior handler was only waiting for I/O on one lun to finish before
returning completion. Now, wait for all LUNs on the target.
Also performed some rudimentary cleanup while in this code.

bbd1ae412c [SCSI] qla2xxx, lfpc: Rename 'state' attribute to 'link_state'
lpfc and qla2xxx overwrite the standard 'state' attribute with
custom callbacks. So rename the custom attributes to 'link_state'
and retain the original meaning of the 'state' attribute.
