Use the new non-coherent DMA API including proper ownership transfers.
This also means we can allocate the memory as DMA_TO_DEVICE instead
of bidirectional.

Switch the 53c700 driver to only use non-coherent descriptor memory if it
really has to because dma_alloc_coherent fails. This doesn't matter for
any of the platforms it runs on currently, but that will change soon.
To help with this two new helpers to transfer ownership to and from the
device are added that abstract the syncing of the non-coherent memory.
The two current bidirectional cases are mapped to transfers to the
device, as that appears to what they are used for. Note that for parisc,
which is the only architecture this driver needs to use non-coherent
memory on, the direction argument of dma_cache_sync is ignored, so this
will not change behavior in any way.

Pull SPDX updates from Greg KH:
"Here are some SPDX-specific changes for 5.10-rc1.
They include:
- driver fixes to make spdxcheck.pl work properly
- add GFDL licenses as "deprecated" but required due to some of our
documentation using them
- add Zlib license as "deprecated" but required because we have code
with this license in the tree.
- convert some drivers to have SPDX identifiers that previously
didn't have them.
All have been in linux-next for a very long time with no reported
issues"

Currently the PHY state is set according to the state of the PHYs after
reset. This is invalid as the PHYs are already re-initialized.
Set PHY state according to the state before the reset instead of after.

Currently sas_resume_ha() is called while resuming the controller to wait
for all suspended PHYs to come up and all the libsas events to be
completed.
There is a scenario which will cause task hung: For direct attach with two
disks connected with two PHYs, disable phy0 before suspending the disk on
phy1 and the controller, then enable phy0 and resume the controller, and
task hung occurs as follows:

If an extra phy0 up happens during resume of the SAS controller, it will
emit a new libsas event (event PORTE_BYTES_DMAED and event
DISCE_DISCOVER_DOMAIN). We will call function scsi_sysfs_add_sdev() in
event DISCE_DISCOVER_DOMAIN, which will call __pm_runtime_set_status() to
resume supplier (host controller). For runtime PM core, if device is in the
resuming state, the later resume request of the device will wait for
previous resume request to complete synchronously. At that point in time
the state of the controller is still resuming as it waits for all libsas
events to be completed, while libsas event DISCE_DISCOVER_DOMAIN is blocked
as the state of the controller is resuming which causes a deadlock.
To avoid the issue, filter out new PHY up events while the controller is
suspended.

Runtime PM of SCSI devices is already supported in SCSI layer, we can
suspend/resume every SCSI device separately. But if there is no link
between hisi_hba and SCSI devices or SCSI targets it will cause issues if
the controller is suspended while SCSI devices are still resuming. Only
when all the SCSI devices under the controller are suspended, the
controller can be suspended. Add the device link between SCSI devices
and the controller.

To support system suspend/resume or runtime suspend/resume, need to use the
function pci_set_power_state() to change the power state which requires at
least method _PS0 or _PR0 be filled by platform for v3 hw. So check whether
the method is supported, if not, print a warning.
A Kconfig dependency is added as there is no stub for
acpi_device_power_manageable().

For v3 hw we will add support for runtime PM which is only supported in new
framework. Legacy PM support and new framework are not allowed to be used
together. Switch to new framework to support suspend and resume.

The reason is that if we use pci_alloc_irq_vectors_affinity() to allocate
IRQs, the number of CQ IRQs can only be less than or equal to the number of
online CPUs, but we use hisi_hba->queue_count (always 16) to iterate during
interrupt_disable_v3_hw().
Use hisi_hba->cq_nvecs to replace hisi_hba->queue_count to avoid
synchronize IRQ on a CPU which does not exist.

The be_fill_queue() function can only fail when "eq_vaddress" is NULL and
since it's non-NULL here that means the function call can't fail. But
imagine if it could, then in that situation we would want to store the
"paddr" so that dma memory can be released.

The fnic drivers assigns an ioreq structure to each command and severs this
assignment once scsi_done() has been called and the command has been
completed.
When traversing commands to terminate outstanding I/O we should not call
scsi_done() on commands which do not have a corresponding ioreq structure;
these commands have either never entered the driver or have already been
completed.

Some iSCSI targets went with the traditional "export N ports" approach and
then allowed the initiator to multipath over them. Other targets went the
opposite direction and export a single port, and then software on the
target side performs load balancing and failover to other targets via an
iSCSI specific feature or IP takover.
The problem for the 2nd type of config is we quickly run out of our five
retries and get I/O errors. In these setups we want to reduce resource use
on the initiator side so we only wanted the one session and no
dm-multipath. To handle traditional multipath operations like failover we
do IP takover on the target side. So we would have an iSCSI target running
on node1. Some monitoring software decides it's dead or the node is
overloaded so it starts the iSCSI target on node2. The problem is for the
failover case where we might have the equivalent of a dm-multipath
temporary all paths down, or we just have to try more than 5 nodes before
finding a good one.
To handle this type of issue allow the user to configure the disk cmd
retries from -1 to the current max of 5. -1 means infinite retries and
should be used for setups where some other setting is going to control when
to fail. For example iSCSI has the replacement/recovery timeout and fc
(some users have used FC with NPIV and done something similar as IP
takover) has dev_loss_tmo/fast_io_fail which will eventually expire and
fail I/O.

Driver was using a shorter timeout waiting for PLOGI from the peer in
point-to-point configurations. Some devices takes some time (~4 seconds) to
initiate the PLOGI. This peer initiating PLOGI is when the peer has a
higher P-WWN.
Increase the wait time based on N2N R_A_TOV.

Normally, the MPI firmware is reset when an MPI dump is collected. If an
unsaved MPI dump exists in the driver, though, an alternate mechanism is
used. This mechanism, which was not fully correct, is not recommended and
instead an MPI dump template walk is suggested to perform the MPI reset.
To allow for the MPI dump template walk, extra space is reserved in the MPI
dump buffer which gets used only when there is already an MPI dump in
place.

When printing the message:
"MPI Heartbeat stop. MPI reset is not needed.."
..the wrong register was checked leading to always printing that MPI reset
is not needed, even when it is needed. Fix the MPI reset message.

Some MediaTek UFS platforms support high-performance mode that inline
encryption engine can be boosted while UFS is not clock-gated.
The high-performance mode will be enabled if all below conditions are
well-declaired in device tree,
- Proper platform-specific compatible string which enables the host
capability "UFS_MTK_CAP_BOOST_CRYPT_ENGINE".
- "dvfsrc-vcore" node is available in this platform.
- Required minimum vcore voltage for high-performance mode.
- Clock mux and clock parents of inline encryption engine for both
"low-power mode" and "high-performance mode".
