Jason Gunthorpe 997c3e6959 iommu: Validate the PASID in iommu_attach_device_pasid() 
[ Upstream commit c404f55c26 ]

The SVA code checks that the PASID is valid for the device when assigning
the PASID to the MM, but the normal PAGING related path does not check it.

Devices that don't support PASID or PASID values too large for the device
should not invoke the driver callback. The drivers should rely on the
core code for this enforcement.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
