[PATCH kernel 1/2] powerpc/pseries/dma: Allow swiotlb

2019-05-06 Thread Alexey Kardashevskiy
The commit 8617a5c5bc00 ("powerpc/dma: handle iommu bypass in dma_iommu_ops") merged direct DMA ops into the IOMMU DMA ops allowing SWIOTLB as well but only for mapping; the unmapping and bouncing parts were left unmodified. This adds missing direct unmapping calls to .unmap_page() and .unmap_sg()
