98cdfb4347 [SCSI] bfa: fix endian and bit field check bug
Fix some endian issue. __BIGENDIAN is not defined and it needs to be
replaced with __BIG_ENDIAN. Also fixed a bug in bit field access.
These two issues were reported by Dan Carpenter.

4507025d01 [SCSI] bfa: DMA memory allocation enhancement.
- Modified the design such that each BFA sub-module will provide
  the amount of DMA and KVA memory needed by it and queues the
  same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
  the dma and kva memory requested by sub-modules.

  message header instead of from cpqe event.
- Made changes to allow using all 256 queues of Brocade-1860 asic.
  Previously only a single queue per queue group was used.
- Added function tag to BFI message header. Only used by FC BFI
  messages.  Used to translate host tag to firmware tag. bfa_lpuid()
  is changed to bfa_fn_lpu() that encodes both PCI function and port
  ID in BFI message header.

  illegal write access to flash controller register domain. Since
  flash controller registers are only accessible once s_clk is started

- Removed unnecessary reset logic for PMM 1T memory and moved memory
  initialization after flash access enable.
- Disable Brocade-1860 asic MBOX interrupt before PLL initialization.

45d7f0cc58 [SCSI] bfa: kdump fix
Root cause: When kernel crashes, bfa IOC state machine and FW doesn't get
a notification and hence are not cleanly shutdown. So registers holding
driver/IOC state information are not reset back to valid disabled/parking
values. This causes subsequent driver initialization to hang during kdump
kernel boot.

Fix description: during the initialization of first PCI function, reset
corresponding register when unclean shutown is detect by reading chip
registers. This will make sure that ioc/fw gets clean re-initialization.

15821f05b7 [SCSI] bfa: io tag handling and minor bug fix.
Fix iotag handling:

1) Update and check io tag for retry case.
2) Clearing upper 3 bits in io tag when an IO completes.
   The 3 upper bits in io tags are used for counting FCP exchange retry.
   Un-cleared bits will cause firmware to access invalid memory when the
   same io tag is used for an IO to a target that doesn't support FCP
   exchange retry.
3) Only check the effective bits when validating an iotag.

Other minor fixes:

1) Added trace to get FC header type with assert of unhandled packet received.
   Ignore the type FC_TYPE_FC_FSS (FC_XS).
2) Fixed the adapter info display check - to check for fcmode flag even.

f3a060ca57 [SCSI] bfa: Store port configuration in flash for persistency.
When the bfa driver is loaded a flogi is sent without the knowledge of
trunking configuration. This normal flogi causes the switch ports
which had trunking enabled to go to persistent offline.  Solution is
to store the port configuration (which has trunking info) in the flash
for persistency. The firmware will read this configuration when the
very first fcport enable is received.

f281233d3e SCSI host lock push-down
Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.

The patch below presents a simple SCSI host lock push-down as an
equivalent transformation.  No locking or other behavior should change
with this patch.  All existing bugs and locking orders are preserved.

Additionally, add one parameter to queuecommand,
	struct Scsi_Host *
and remove one parameter from queuecommand,
	void (*done)(struct scsi_cmnd *)

Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.

Minimal code disturbance was attempted with this change.  Most drivers
needed only two one-line modifications for their host lock push-down.

c54d557c3f [SCSI] bfa: vport fixes
This patch fixes 3 bugs in vport create/delete.
1) Replace scsi_add_host() with scsi_add_host_with_dma()
2) Fix rmmod hang when there are vports configured. This is due to a race
condition between the workqueue destroy in pci remove context and the vport
delete works being handled. The fix is to use a counter to track the
vport delete work, so that workqueue destroy will not be called until all
configured vports are deleted from workqueue.
3) Fix rmmmod crash when there are PBC vport configured. PBC is not allowed
to be deleted dynamically. However, if someone try to delete it, it leaves the
vport is wrong state. The fix is to restore the vport back to original state
when the attempt to delete pbc vport delete is failed.

56d218fc93 [SCSI] bfa: fix possible IO double completion
While processing the ioim in callback functions, the ioim is still in io_q.
During this time, if the itnim goes offline, the ioim is requeued from
itnim->io_q into itnim->delay_comp_q although the request is already completed.
This results in requeing the ioim into the callback queue if the ioim is not
freed by the time the ioim is requeued. This results in double completion of
the ioim. To fix this, whenever a response is received from firmware for an
ioim, deque it from io_q and enque to fcpim->comp_q. This will eliminate any
possibility of itnim picking any ioim for which the response is already
received.

db954c04cb [SCSI] bfa: fix link state structure
When the FCoE Linkup event is sent to the host, the link_state
(struct bfa_pport_link_s) structure is copied to the RME buf to be sent to
the host. But the size of this structure(164 bytes) is larger than the
reserved RME buffer size(128 byes). The following changes reduce the size
of the structure to be less than RME buffer size(128 bytes):
- Remove the trunk and loop info from link_state structure, because both trunk
  and loop are not supported.
- Combine qos_vc_attr and fcf into an union.

4b5e759dca [SCSI] bfa: fix uf post and rport fcpim state machine
BFA UF module did not hold lock when seding uf post buffer message to firmware
causing CPE-Q corruption. Fix is to check present of FCS and if FCS present
hold lock while posting UF buffers.

Handle PRLO with sending acc to it and relogin with rport. Discard fcxp
before any state change.

df2a52a6c8 [SCSI] bfa: fix chip and memory initialization
Clear PSS memory reset that is set as part of power-on-reset (pci reset).
Complete PMM memory reset before BISTR start. Clear EDRAM BISTR start bit
after fixed delay. BISTR DONE bit status is not getting set. Use a fixed
1ms delay for BISTR now. Expose PMM IT memory definitions to host.
