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

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':

Fixed up trivial conflict due to moving the async part of sd_probe
around in the async probes vs using dev_set_name() in naming.
In each case, if the NULL test is necessary, then the dereference should be
moved below the NULL test.

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.
