Hi Lorenzo,

To defeat ACPICA<->kernel merge order dependencies a preprocessor define
value was introduced in the IORT compilation unit according to IORT
revision C, IORT_SMMU_V3_CAVIUM_CN99XX, so that even if the value was
not defined in ACPICA headers the IORT kernel layer would still be able
to function and use it.

Since commit 0c2021c047ba ("ACPICA: IORT: Update SMMU models for
revision C") finally added the define in ACPICA headers, as required by
ACPICA IORT support, the preprocessor definition in the IORT kernel
compilation unit has become obsolete and can be removed.

Can the version check around iort_get_id_mapping_index() go as well?

Gone :) (just did two patches since they were part of different
changes), I will batch them up and send them in a pull request for
v4.17.

Ah, cool - I hadn't see that one go by.

For this one (and the other as well if you like):
