[ Upstream commit 8f880d19e6ad645a4b8066d5ff091c980b3231e7 ]
With the addition of the V2 page table support, the domain page size
bitmap needs to be set prior to iommu core setting up direct mappings
for reserved regions. When reserved regions are mapped, if this is not
done, it will be looking at the V1 page size bitmap when determining
the page size to use in iommu_pgsize(). When it gets into the actual
amd mapping code, a check of see if the page size is supported can
fail, because at that point it is checking it against the V2 page size
bitmap which only supports 4K, 2M, and 1G.
Add a check to __iommu_domain_alloc() to not override the
bitmap if it was already set by the iommu ops domain_alloc() code path.

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.
