In anticipation of the removal of the msi_controller structure, convert
the ancient xilinx host controller driver to MSI domains.
We end-up with the usual two domain structure, the top one being a
generic PCI/MSI domain, the bottom one being xilinx-specific and handling
the actual HW interrupt allocation.
This allows us to fix some of the most appaling MSI programming, where
the message programmed in the device is the virtual IRQ number instead
of the allocated vector number. The allocator is also made safe with
a mutex. This should allow support for MultiMSI, but I decided not to
even try, since I cannot test it.

A long cargo-culted behaviour of PCI drivers is to allocate memory
to obtain an address that is fed to the controller as the MSI
capture address (i.e. the MSI doorbell).
But there is no actual requirement for this address to be RAM.
All it needs to be is a suitable aligned address that will
*not* be DMA'd to.
Use the physical address of the 'port' data structure as the MSI
capture address, aligned on a 4K boundary.

But there is no actual requirement for this address to be RAM.
All it needs to be is a suitable aligned address that will

Since the rcar platform already has a requirement that this
address should be in the first 4GB of the physical address space,
use the controller's own base address as the capture address.

In anticipation of the removal of the msi_controller structure, convert
the Tegra host controller driver to MSI domains.
We end-up with the usual two domain structure, the top one being a
generic PCI/MSI domain, the bottom one being Tegra-specific and handling
the actual HW interrupt allocation.
While at it, convert the normal interrupt handler to a chained handler,
handle the controller's MSI IRQ edge triggered, support multiple MSIs
per device and use the AFI_MSI_EN_VEC* registers to provide MSI masking.

Currently when GID is deleted, it zero out all the fields of the RoCE
address in the SET_ROCE_ADDRESS command for a specified index.
roce_version = 0 means RoCEv1 in the SET_ROCE_ADDRESS command.
This assumes that device has RoCEv1 always enabled which is not always
correct. For example Subfunction does not support RoCEv1.
Due to this assumption a previously added RoCEv2 GID is always deleted as
RoCEv1 GID. This results in a below syndrome:
mlx5_core.sf mlx5_core.sf.4: mlx5_cmd_check:777:(pid 4256): SET_ROCE_ADDRESS(0x761) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x12822d)
Hence set the right RoCE version during GID deletion provided by the core.

There is no need to have an additional bus for the IAX device. The removal
of IAX will change user ABI as /sys/bus/iax will no longer exist.
The iax device will be moved to the dsa bus. The device id for dsa and
iax will now be combined rather than unique for each device type in order
to accommodate the iax devices. This is in preparation for fixing the
sub-driver code for idxd. There's no hardware deployment for Sapphire
Rapids platform yet, which means that users have no reason to have
developed scripts against this ABI. There is some exposure to
released versions of accel-config, but those are being fixed up and
an accel-config upgrade is reasonable to get IAX support. As far as
accel-config is concerned IAX support starts when these devices appear
under /sys/bus/dsa, and old accel-config just assumes that an empty /
missing /sys/bus/iax just means a lack of platform support.

The char device setup and cleanup has device lifetime issues regarding when
parts are initialized and cleaned up. The initialization of struct device is
done incorrectly. device_initialize() needs to be called on the 'struct
device' and then additional changes can be added. The ->release() function
needs to be setup via device_type before dev_set_name() to allow proper
cleanup. The change re-parents the cdev under the wq->conf_dev to get
natural reference inheritance. No known dependency on the old device path exists.

On Intel processors, the core frequency can be reduced below OS request,
when the current temperature reaches the TCC (Thermal Control Circuit)
activation temperature.
The default TCC activation temperature is specified by
MSR_IA32_TEMPERATURE_TARGET. However, it can be adjusted by specifying an
offset in degrees C, using the TCC Offset bits in the same MSR register.
This patch introduces a cooling devices driver that utilizes the TCC
Offset feature. The bigger the current cooling state is, the lower the
effective TCC activation temperature is, so that the processors can be
throttled earlier before system critical overheats.
Note that, on different platforms, the behavior might be different on
how fast the setting takes effect, and how much the CPU frequency is
reduced.
This patch has been tested on a KabyLake mobile platform from me, and also
on a CometLake platform from Doug.

When using SW steering, rule insertion rate depends on the RDMA RC QP
performance used for writing to the ICM. During stress this QP is competing
on the HW resources with all the other QPs that are used to send data.
To protect SW steering QP's performance in such cases, we set this QP to
use isolated VL. The VL number is reserved by FW and is not exposed to the
driver.
Support for this QP on isolated VL exists only when both force-loopback and
isolate_vl_tc capabilities are set.

When supported by the device, SW steering RoCE RC QP that is used to
write/read to/from ICM will be created with force-loopback attribute.
Such QP doesn't require GID index upon creation.

Flex parser is a HW parser that can support protocols that are not
natively supported by the HCA, such as Geneve (TLV options) and GTP-U.
There are 8 such parsers, and each of them can be assigned to parse a
specific set of protocols.
This patch adds misc4 match params which allows using a correct flex parser
that was programmed to the required protocol.

Add error code to the error messages and removed duplicated message:
if termination table creation failed, we already get an error message
in mlx5_eswitch_termtbl_create, so no need for the additional error print
