Caused by:
e93a1695d7fb ("iommu: Enable compile testing for some of drivers")
Which did:
config SPAPR_TCE_IOMMU
bool "sPAPR TCE IOMMU Support"
- depends on PPC_POWERNV || PPC_PSERIES
+ depends on PPC_POWERNV || PPC_PSERIES || (PPC && COMPILE_TEST)
Which is just ... not right, the dependencies on the correct platform
are important, otherwise the build breaks.
