Brian King	ac9af7cba9	[PATCH] ppc64: iommu vmerge fix 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.

[PATCH] ppc64: iommu vmerge fix

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.

[PATCH] initialize TCE tables

A fairly recent platform requirement states that the OS must clear the
whole TCE table at setup time, in case firmware left any active
mappings in it.  Without this initialization, dynamic bus removes can
fail.  Firmware rejects these requests if active mappings still exist 
for a slot that has been deallocated by the OS.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
