The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below.
It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.
It has been compile tested.

HiSilicon KunPeng920 and KunPeng930 have devices that appear as PCI but are
actually on the AMBA bus. These fake PCI devices can support SVA via the
SMMU stall feature.
DT systems can indicate this in the device tree, but ACPI systems don't
have that mechanism, so add a "dma-can-stall" property manually for them.

The switch statement in the artpec6_pcie_probe() has a local code block
where "val" is defined and immediately used by the artpec6_pcie_readl().
This extra code block adds brackets at the same indentation level as the
switch statement itself which can hinder readability of the code.
Move the "val" declaration to the top of the function and remove
the extra code block from the switch statement.

Previously we assumed that all Root Ports and Switch Downstream Ports
supported Link Bandwidth Notification. Per spec, this is only required
for Ports supporting Links wider than x1 and/or multiple Link speeds
(PCIe r5.0, sec 7.5.3.6).
Because we assumed all Ports supported it, we tried to set up a Bandwidth
Notification IRQ, which failed for devices that don't support IRQs at all,
which meant pcieport didn't attach to the Port at all.
Check the Link Bandwidth Notification Capability bit and enable the service
only when the Port supports it.

Some systems, e.g., HiSilicon KunPeng920 and KunPeng930, have devices that
appear as PCI but are actually on the AMBA bus. Some of these fake PCI
devices support a PASID-like feature and they do have a working PASID
capability even though they do not use the PCIe Transport Layer Protocol
and do not support TLP prefixes.
Add a pasid_no_tlp bit for this "PASID works without TLP prefixes" case and
update pci_enable_pasid() so it can enable PASID on these devices.
Set this bit for HiSilicon KunPeng920 and KunPeng930.

Use pci_vpd_alloc() to dynamically allocate a properly sized buffer and
read the full VPD data into it.
This simplifies the code, and we no longer have to make assumptions about
VPD size.

Use strncasecmp() to match Vendor ID instead of comparing with lower- and
upper-case hex string.

Read NVRAM directly into buffer and use swab32s() to byte swap it in-place
instead of reading it into the end of the buffer and swapping it manually
while copying it.

Replace netif_err() with pci_err() because the netdevice isn't registered
yet, which results in very ugly messages.
Use kmemdup_nul() instead of open-coding it.
This is the same as 37838aa437c7 ("sfc: Search VPD with
pci_vpd_find_ro_info_keyword()"), just for the falcon chip version.

Use pci_vpd_alloc() to dynamically allocate a properly sized buffer and
read the full VPD data into it.
This avoids having to allocate a buffer on the stack, and we don't have to
make any assumptions on VPD size and location of information in VPD.
This is the same as 5119e20facfa ("sfc: Read VPD with pci_vpd_alloc()"),
just for the falcon chip version.

Now we have everything we need, just provide a proper sysdata type for
the bus to use on ARM64 and everything else works.
