      "title": "parisc: fix a possible DMA corruption",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nparisc: fix a possible DMA corruption\n\nARCH_DMA_MINALIGN was defined as 16 - this is too small - it may be\npossible that two unrelated 16-byte allocations share a cache line. If\none of these allocations is written using DMA and the other is written\nusing cached write, the value that was written with DMA may be\ncorrupted.\n\nThis commit changes ARCH_DMA_MINALIGN to be 128 on PA20 and 32 on PA1.1 -\nthat's the largest possible cache line size.\n\nAs different parisc microarchitectures have different cache line size, we\ndefine arch_slab_minalign(), cache_line_size() and\ndma_get_cache_alignment() so that the kernel may tune slab cache\nparameters dynamically, based on the detected cache line size.",
