Nested translation mode is supported in VT-d 3.0 Spec.CH 3.8.
With PASID granular translation type set to 0x11b, translation
result from the first level(FL) also subject to a second level(SL)
page table translation. This mode is used for SVA virtualization,
where FL performs guest virtual to guest physical translation and
SL performs guest physical to host physical translation.
This patch adds a helper function for setting up nested translation
where second level comes from a domain and first level comes from
a guest PGD.

An Intel iommu domain uses 5-level page table by default. If the iommu
that the domain tries to attach supports less page levels, the top level
page tables should be skipped. Add a helper to do this so that it could

Current Intel IOMMU driver sets the system level dma_ops. This causes
each dma API to go through the IOMMU driver even the devices are using
identity mapped domains. This sets per-device dma_ops only if a device
is using a DMA domain. Otherwise, use the default system level dma_ops

Before commit fa954e6831 ("iommu/vt-d: Delegate the dma domain
to upper layer"), Intel IOMMU started off with all devices in the
identity domain, and took them out later if it found they couldn't
access all of memory. This required devices behind a PCI bridge to
use a DMA domain at the beginning because all PCI devices behind
the bridge use the same source-id in their transactions and the
domain couldn't be changed at run-time.
Intel IOMMU driver is now aligned with the default domain framework,
there's no need to keep this requirement anymore.

Currently, if a 32bit device initially uses an identity domain, Intel
IOMMU driver will convert it forcibly to a DMA one if its address
capability is not enough for the whole system memory. The motivation was
to overcome the overhead caused by possible bounced buffer.
Unfortunately, this improvement has led to many problems. For example,
some 32bit devices are required to use an identity domain, forcing them
to use DMA domain will cause the device not to work anymore. On the
other hand, the VMD sub-devices share a domain but each sub-device might
have different address capability. Forcing a VMD sub-device to use DMA
domain blindly will impact the operation of other sub-devices without
any notification. Further more, PCI aliased devices (PCI bridge and all
devices beneath it, VMD devices and various devices quirked with
pci_add_dma_alias()) must use the same domain. Forcing one device to
switch to DMA domain during runtime will cause in-fligh DMAs for other
devices to abort or target to other memory which might cause undefind
system behavior.
With the last private domain usage in iommu_need_mapping() removed, all
private domain helpers are also cleaned in this patch. Otherwise, the
compiler will complain that some functions are defined but not used.

The host1x bus implemented on Tegra SoCs is primarily an abstraction to
create logical device from multiple platform devices. Since the devices
in such a setup are typically hierarchical, DMA setup still needs to be
done so that DMA masks can be properly inherited, but we don't actually
want to attach the host1x logical devices to any IOMMU. The platform
devices that make up the logical device are responsible for memory bus
transactions, so it is them that will need to be attached to the IOMMU.
Add a check to __iommu_probe_device() that aborts IOMMU setup early for
busses that don't have the IOMMU operations pointer set since they will
cause a crash otherwise.

When a bus is initialized with iommu-ops, all devices on the bus are
scanned and iommu-groups are allocated for them, and each groups will
also get a default domain allocated.
Until now this happened as soon as the group was created and the first
device added to it. When other devices with different default domain
requirements were added to the group later on, the default domain was
re-allocated, if possible.
This resulted in some back and forth and unnecessary allocations, so
change the flow to defer default domain allocation until all devices
have been added to their respective IOMMU groups.
The default domains are allocated for newly allocated groups after
each device on the bus is handled and was probed by the IOMMU driver.

Some devices are reqired to use a specific type (identity or dma)
of default domain when they are used with a vendor iommu. When the
system level default domain type is different from it, the vendor
iommu driver has to request a new default domain with
iommu_request_dma_domain_for_dev() and iommu_request_dm_for_dev()
in the add_dev() callback. Unfortunately, these two helpers only
work when the group hasn't been assigned to any other devices,
hence, some vendor iommu driver has to use a private domain if
it fails to request a new default one.
This adds def_domain_type() callback in the iommu_ops, so that
any special requirement of default domain for a device could be
aware by the iommu generic layer.
