This patch uses dma_map_sg with phba->pcidev->dev instead of
scsi_dma_map.
scsi_dma_map doesn't work for NPIV since fc_vport->dev isn't fully
initialized. check_addr() in arch/x86_64/kernel/pci-nommu.c leads to
the crash since dev->dma_mask is NULL.

The Dell PERC2/QC erroneously was listed as having the 31 bit limit
quirk on the interface allocations, removing the reference to repair
this oversight. Also, the 2 quad pci address (family) match catch-all
also retained the 31 bit limit and the 34 SG limit quirks in a paranoid
move. Now, many years later, we find that none of the Adapters that did
trigger with the family match had such quirks; these quirks are all
limited to the 4 quad pci address matches to select legacy adapters
already populated.

This patch is more like a spelling correction than a fix. It was
discovered that if we had a busy status return from the Adapter for the
SCSI srb command to a physical component, that we returned
DID_NO_CONNECT rather than what one would expect DID_BUS_BUSY.

Following the NPIV support, the following changes have been accumulated
in the testing and qualification of the driver:
- Fix affinity of ELS ring to slow/deferred event processing
- Fix Ring attention masks
- Defer dev_loss_tmo timeout handling to worker thread
- Consolidate link down error classification for better error checking
- Remove unused/deprecated nlp_initiator_tmr timer
- Fix for async scan - move adapter init code back into pci_probe_one
context. Fix async scan interfaces.
- Expand validation of ability to create vports
- Extract VPI resource cnt from firmware
- Tuning of Login/Reject policies to better deal with overwhelmned targets
- Misc ELS and discovery fixes
- Export the npiv_enable attribute to sysfs
- Mailbox handling fix
- Add debugfs support
- A few other small misc fixes:
- wrong return values, double-frees, bad locking
- Added adapter failure heartbeat

NPIV support is added to the driver. It utilizes the interfaces of
the fc transport for the creation and deletion of vports. Within the
driver, a new Scsi_Host is created for each NPIV instance, and is
paired with a new instance of a FC port. This allows N FC Port
elements to share a single Adapter.

NPIV support is only available via new adapter interface extensions,
termed SLI-3. This interface changes some of the basic behaviors such
as command and response ring element sizes and data structures, as
well as a change in buffer posting. Note: the new firmware extensions
are found only on our mid-range and enterprise 4Gig adapters - so NPIV
support is available only on these newer adapters. The latest firmware
can be downloaded from the Emulex support page.

The driver is reorganized to separate the handling of the adapter from
the handling of the FC port. Adapter handling includes submissions of
command requests, receiving responses, and managing adapter resources.
The FC port includes the discovery engine, login handling, and the
mapping of a Scsi_Host on the "port". Although not a large functional
change, as it touches core structures and functions, resulting in a
large text delta.

If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume. In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.

I was investigating strange driver behaviour and thought that readable
code and proper visible types might help explain why it didn't work right
the moment a second SCB was outstanding to the controller. I was right
- Cleanup, linuxise, demacro
- Remove the BSD dual licence on the new work
- Switch the if ALPHA to if __LP64__. (struct size is then right
elsewhere) and then to CONFIG_64BIT as per Christoph's request
- Fix the recursive locking on a reset. This is the only actual real code
change (I hope ;)).
I'm not clear what the right way to handle the BIOS param stuff is on n
on x86-32/64. Using phys_to_virt and stuff is ugly and probably doesn't
make sense elsewhere
Still has a couple of odd things - and there seems to be a commonly shared
EEPROM handling error several drivers have. Roughly speaking several SCSI
drivers go
try and read EEPROM
It failed..
Write any changes between the default and the data we read
Which is great as for some paths we've no idea what was in
before, so each boot won't write it all back, won't checksum but will
repeat the bug
Also it can still sleep for a second with IRQ off, and there is some
dubious looking error path locking marked FIXME in case anyone feels
inspired to work on it. Not a newly introduced bug, and at least its now
marked.

When a target scan is initiated from sysfs, we should check the
portstate prior to invoke scsi_scan_target().
Otherwise scsi_scan_target() might oops as the rport might already
been removed from the scsi host and the traversal from the rport to
the scsi_host in scsi_scan_target() will fail.
Also the portstate already told us that communication with the target
has failed, so it's quite pointless to try.
