This doesn't build:

arch/powerpc/platforms/pseries/iommu.c:652:3: error: 'struct iommu_table_ops' has no member named 'exchange'
  .exchange = tce_exchange_pseries,
   ^~~~~~~~
arch/powerpc/platforms/pseries/iommu.c:652:14: error: initialization of 'int (*)(struct iommu_table *, long int,  long unsigned int *, enum dma_data_direction *, bool)' {aka 'int (*)(struct iommu_table *, long int,  long unsigned int *, enum dma_data_direction *, _Bool)'} from incompatible pointer type 'int (*)(struct iommu_table *, long int,  long unsigned int *, enum dma_data_direction *)' [-Werror=incompatible-pointer-types]
  .exchange = tce_exchange_pseries,
              ^~~~~~~~~~~~~~~~~~~~
