Revision ac9af7cba9e642961bfdee1a1fac6060405597e5 authored by Brian King on 17 August 2005, 21:32:18 UTC, committed by Linus Torvalds on 17 August 2005, 21:41:22 UTC
This fixes a bug in the PPC64 iommu vmerge code which results in the
potential for iommu_unmap_sg to go off unmapping more than it should.

This was found on a test system which resulted in PCI bus errors due to
PCI memory being unmapped while DMAs were still in progress.
