Apple silicon SoCs have numerous embedded co-processors with pre-loaded firmware. The co-processors text and data sections need to be mapped via DART iommus controlled by the main processor. Those sections are exported as reserved-memory. Bump CONFIG_LMB_MAX_REGIONS from 8 to 64 to deal with the large amount of reserved-memory regions.
We recently bumped the default for CONFIG_LMB_MAX_REGIONS from 8 to 16, but 64 would be a safer value for this platform as there are more co-processor drivers in the pipeline that may add reserved-memory regions. These machines have plenty of memory.

Does this mean it's a fix we need for v2023.04, or v2023.07 is OK?
2023.07 is ok
