The check to set identity map for tylersburg is done too late. It needs
to be done before the check for identity_map domain is done.

Resending Jean's patch so it can be included earlier than his large
SVM commits. Original patch https://patchwork.kernel.org/patch/9593891
was ack'ed by Bjorn. Let's commit these separately since we need
functionality earlier.
Resending this series as requested by Jean.

Hi
Sorry for resending.. iommu list email was mistyped :-(
The first 2 patches in the series fix some simple bugs in Intel vt-d driver.
The 3rd patch Adds support for kmem notify required to support ring0 SVM.
4th patch uses the hooks to perform device tlb invalidations.

Presently, the default domain of an iommu group is allocated during boot time
and it cannot be changed later. So, the device would typically be either in
identity (pass_through) mode or the device would be in DMA mode as long as the
system is up and running. There is no way to change the default do
From: Sai Praneeth Prakhya
The default domain type of an iommu group can be changed by writing to
"/sys/kernel/iommu_groups//type" file. Hence, document it's usage
and more importantly spell out its limitations.

PCI_INTERRUPT_PIN should always read 0 for SRIOV Virtual Functions.
Some SRIOV devices have some bugs in RTL and VF's end up reading 1
instead of 0 for the PIN.
We could enforce it by default in vfio_pci_nointx.
