The obsolete per iommu pasid tables are no longer used. Hence,
clean up them.

This patch allocates a PASID table for a PCI device at the time
when the dmar dev_info is attached to dev->archdata.iommu, and
free it in the opposite case.

This patch adds the interfaces for per PCI device pasid
table management. Currently we allocate one pasid table
for all PCI devices under the scope of an IOMMU. It's
insecure in some cases where multiple devices under one
single IOMMU unit support PASID features. With per PCI
device pasid table, we
This adds a helper named for_each_device_domain() to iterate
over the elements in device_domain_list and invoke a callback
against each element. This allows to search the device_domain
list in other source files.

Hi Linus,
below is a rename of the assorted dma-mapping files to that they live
under kernel/dma and lose their dma-* prefixes. If there is any time
to do this it is right after -rc1, so let me know if this is something
you'd take.

When drivers call intel_svm_available() to check whether the
Shared Virtual Memory(SVM) is supported by the IOMMU driver,
they will get a warning in the kernel message if the SVM is
not supported by the hardware.

Commit 4b123757eeaa ("iommu/io-pgtable-arm: Make allocations
NUMA-aware") added a NUMA hint to page table allocation, but the pgtable
selftest doesn't provide an SMMU device parameter. Since dev_to_node
doesn't accept a NULL argument, add a special case for selftest.
