  Linux 3.1-rc4 (2011-08-28 21:16:01 -0700)

are available in the git repository at:
  git://git.8bytes.org/scm/iommu.git amd/fixes

Joerg Roedel (2):
      iommu/amd: Make sure iommu->need_sync contains correct value
      iommu/amd: Don't take domain->lock recursivly

 1 files changed, 10 insertions(+), 8 deletions(-)

These patches fix a performance regression because of too many
unnecessary completion-wait commands being sent and a dead-lock
situation for drivers that allocate more than 1GB of dma address space.
Please pull.

Regards,

	Joerg
