Logan Gunthorpe 028926e4ac dmaengine: ioat: Allocate correct size for descriptor chunk ... dma_alloc_coherent() is called with a fixed SZ_2M size, but frees happen with IOAT_CHUNK_SIZE. Recently, IOAT_CHUNK_SIZE was reduced to 512M but the allocation did not change. To fix, change to using the IOAT_CHUNK_SIZE define. This was caught with the upcoming patchset for converting Intel platforms to the dma-iommu implementation. It has a warning when the unmapped size differs from the mapped size.
