Ok, here's a patch to add such a common API for fc transport users.
Relevant LLD changes (lpfc and qla2xxx) also present.

Replace use of lpfc_put_lun with midlayer's int_to_scsilun
Remove driver's local definition of lpfc_put_lun (which converts an
int back to a 64-bit LUN) and replace it's use with the recently added
int_to_scsilun function provided by the midlayer.
Note: Embedding midlayer structure in our structure caused
need for more files to include midlayer headers.

Fix handling of the dev_loss and nodev timeouts.
Symptoms: when remote port disappears for a period of time longer then
either nodev_tmo or dev_loss_tmo, the lpfc driver worker thread will
stall removing that remote port.
Cause: removing remote port involves un-blocking and sync-ing
corresponding block device queue. But corresponding node in the lpfc
driver is still in the NPR(?node port recovery?) state and mid-layer
gets SCSI_MLQUEUE_HOST_BUSY as a return value when it is trying to call
queuecommand() with command for that node (AKA remote port)
Fix: Instead of returning SCSI_MLQUEUE_HOST_BUS from queuecommand() for
nodes in NPR states complete it with retry-able error code DID_BUS_BUSY

Fix panic in lpfc_get_stats()
Symptoms: Panic on sysfs stats access
Cause: In lpfc_get_stats() we are writing to memory that we do not
own.
Fix: Fix our stats structure allocation. Embed phba->link_stats in
struct lpfc_hba and stop treating it like rogue structure.
Note: Embedding midlayer/transport structure in our structure caused
need for more files to include midlayer/transport headers.

Clear task management bits when preparing SCSI commands
In lpfc_scsi_prep_cmnd, clear the task management bits (fcpCntl2 member
in the fcp_cmd structure) when preparing regular SCSI commands.

Fix panic on lip and cable pull
Symptoms: Panic on lip or cable pull
Cause: Use after free of nlp in lpfc_nlp_remove()
Fix: Do not make FC transport calls after a node is removed. Transport
calls are disabled by ignoring the initial delete transition.

IOCB BDE not getting fully initialized during reuse
Symptoms: Driver gets Status 3 and Reason 0x13 on IOCB completions.
Cause: The IOCB bpl.bdeSize and bdeFlags are not getting initialized on reuse.
Fix: Reinitialize these fields in prep_dma each time an IOCB is used.

Symptom - An unmapped node (initiator) that goes away in a situation
such as cable pull, comes back as a mapped node. Fix - On ADISC
completion, put a list on the mapped list only if it is a FCP_TARGET.

lpfc_els_unsol_event() checks rjt_err to determine is LS_RJT should be
sent. However, rjt_err was set to LSEXP_NOTHING_ELSE (which is 0) in
cases where an LS_RJT should be sent, so rjt_err was never true.
Change lpfc_els_unsol_event() to set rjt_err to 1 when LS_RJT should
be sent.

Fix driver not seeing LP6000. Fix: add PCI id to the pci_device_id
table and a short description for the HBA in get_hba_model_desc().
Also add a default clause to the switch statement that parses the

Add max_sectors to the driver host template and initialize it with
0xFFFF since the driver has no limitations on the size a transfer
contained by a scsi command and that fits within the sg_tablesize
provisioned by the driver. This fixes a performance issue seen in
some configurations.

Analysis:
Timeout of READ_SPARM64 causes call to lpfc_mbox_timeout_handler which
reads psli->mbox_active to determine the timeout mbox. Timeout
handler then NULL's psli->mbox_active and calls
lpfc_mbx_cmpl_read_sparam(), which on timeout condition, calls
link_down(). link_down() now calls disc_done() which calls
mbox_timeout_hander() again since WORKER_MBOX_TMO is still set, which
goes back to read psli->mbox_active which is already NULL'ed.
Remove redundant if statement in lpfc_mbox_timeout_handler. pmbox is
assigned psli->mbox_active so there is no need to check if it actually
equals psli->mbox_active.

From: Christoph Hellwig <hch@lst.de>:
- rename PGP/HPH to lpfc_pgp/lpfc_hgp
- use __le32 types for the members to start fixing sparse -Wbitwise
issues
- remove lpfc_sli.MBhostaddr, we can always use the pointer from
SLI2_DESC directly
