The powernv platform maintains 2 TCE tables for VFIO - a hardware TCE table and a table with userspace addresses; the latter is used for marking pages dirty when corresponging TCEs are unmapped from the hardware table.a68bd1267b("powerpc/powernv/ioda: Allocate indirect TCE levels on demand") enabled on-demand allocation of the hardware table, however it missed the other table so it has still been fully allocated at the boot time. This fixes the issue by allocating a single level, just like we do for the hardware table.

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.
