The warning you already quoted in your changelog is sufficient warning
that the SLIT is bad and it suppresses setting that distance. Your
change, however, completely invalidates the SRAT if the number of
localities does not match the number of pxms. We'd much rather simply
suppress the bad distance rather than invalidate the SRAT, especially
considering there is nothing in the ACPI spec that requires it.
