... except that it doesn't build:


drivers/acpi/arm64/iort.c: In function ?arm_smmu_v3_resource_size?:
drivers/acpi/arm64/iort.c:837:21: error: ?ACPI_IORT_SMMU_V3_CAVIUM_CN99XX? undeclared (first use in this function)
  if (smmu->model == ACPI_IORT_SMMU_V3_CAVIUM_CN99XX)
                     ^
drivers/acpi/arm64/iort.c:837:21: note: each undeclared identifier is reported only once for each function it appears in
make[4]: *** [drivers/acpi/arm64/iort.o] Error 1


I don't see ACPI_IORT_SMMU_V3_CAVIUM_CN99XX defined, even in linux-next.

What's the plan here?
