  iommu/amd: Fix deadlock in ppr-handling error path (2012-06-04 12:47:44 +0200)

----------------------------------------------------------------
IOMMU fixes for v3.5-rc1

Two patches are in here which fix AMD IOMMU specific issues. One patch
fixes a long-standing warning on resume because the amd_iommu_resume
function enabled interrupts. The other patch fixes a deadlock in an
error-path of the page-fault request handling code of the IOMMU driver.

  iommu/amd: fix type bug in flush code (2012-07-02 12:11:40 +0200)

----------------------------------------------------------------
IOMMU fixes for Linux v3.5-rc5

The patches fix several issues in the AMD IOMMU driver, the NVidia SMMU
driver, and the DMA debug code. The most important fix for the AMD IOMMU
solves a problem with SR-IOV devices where virtual functions did not
work with IOMMU enabled. The NVidia SMMU patch fixes a possible sleep
while spin-lock situation (queued the small fix for v3.5, a better but
more intrusive fix is coming for v3.6). The DMA debug patches fix a
possible data corruption issue due to bool vs. u32 usage.
