Depending on the target architecture and configuration, both phys_addr_t
and dma_addr_t may be smaller than 'long long', so we get a warning when
printing either of them using the %llx format string:

drivers/scsi/qla2xxx/qla_iocb.c:1140:46: error: format '%llx' expects argument of type 'long long unsigned int', but argument 6 has type 'dma_addr_t' {aka 'unsigned int'} [-Werror=format=]

~~~^
There are special %pad and %pap format strings in Linux that we could use
here, but since the driver already does 64-bit arithmetic on the values,
using a plain 'u64' seems more consistent here.
Note: A possible related issue may be that the driver possibly checks the
wrong kind of overflow: when an IOMMU is in use, buffers that cross a
32-bit boundary in physical addresses would still be mapped into dma
addresses within the low 4GB space, so I suspect that we actually want to
check sg_dma_address() instead of sg_phys() here.

Currently code performs a full scan of the fabric for

This patch optimizes expensive fabric discovery process by
scanning switch for the affected port when RSCN is received.
Currently Initiator Mode code makes login/logout decision without
knowledge of target mode. This causes driver and firmware to go
out-of-sync. This framework synchronizes both initiator mode
personality and target mode personality in making login/logout
decision.
This patch adds following capabilities in the driver
- Send Notification Acknowledgement asynchronously.
- Update session/fcport state asynchronously.
- Create a session or fcport struct asynchronously.
- Send GNL asynchronously. The command will ask FW to
provide a list of FC Port entries FW knows about.
- Send GPDB asynchronously. The command will ask FW to
provide detail data of an FC Port FW knows about or
perform ADISC to verify the state of the session.
- Send GPNID asynchronously. The command will ask switch
to provide WWPN for provided NPort ID.
- Send GPSC asynchronously. The command will ask switch
to provide registered port speed for provided WWPN.
- Send GIDPN asynchronously. The command will ask the
switch to provide Nport ID for provided WWPN.
- In driver unload path, schedule all session for deletion
and wait for deletion to complete before allowing driver

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley:
"This includes one new driver: cxlflash plus the usual grab bag of
updates for the major drivers: qla2xxx, ipr, storvsc, pm80xx, hptiop,
plus a few assorted fixes.
There's another tranch coming, but I want to incubate it another few
days in the checkers, plus it includes a mpt2sas separated lifetime
fix, which Avago won't get done testing until Friday"

This patch removes 21 casts between an __iomem pointer type and
another data type but also introduces five new casts (see also
the casts with "__force"). Although this patch does not change
any functionality, IMHO the code with __force casts needs further
review.
