"powerpc/kernel/iommu: Align size for IOMMU_PAGE_SIZE() to save TCEs" # # This reverts commit 3c0468d4451eb6b4f6604370639f163f9637a479. # # That commit was breaking alignment guarantees for the DMA address when # allocating coherent mappings, as described in # Documentation/core-api/dma-api-howto.rst # # It was also noticed by Mellanox' driver: # [ 1515.763621] mlx5_core c002:01:00.0:
