Benjamin Herrenschmidt eeac5c142b [POWERPC] Fix G5 DART (IOMMU) race causing occasional data corruption ... It seems that the occasional data corruption observed with the tg3 driver wasn't due to missing barriers after all, but rather seems to be due to the DART (= IOMMU) in the U4 northbridge reading stale IOMMU table entries from memory due to a race. This fixes it by making the CPU read the entry back from memory before using it.
