  "message": "[PATCH] powerpc: IOMMU SG paranoia\n\nThis addresses two items, which are unlikely to be hit if we\ntrust drivers.\n\nThe first is moving a memory barrier below where the vmerged SG count\nis passed back, but before the list is set to end.  If those\ninstructions were reordered, there could be an issue in iommu_unmap_sg().\n\nThe second is making sure we terminate the list on the failure case of\niommu_map_sg().  If a driver does not look at the failure return code,\nit could pass a ill-formed SG list to iommu_unmap_sg().\n\nSigned-off-by: Jake Moilanen \u003cmoilanen@austin.ibm.com\u003e\nAcked-by: Olof Johansson \u003colof@lixom.net\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n",
