kvmppc_e500_ref_setup is returning whether the guest TLB entry is writable, which is than passed to kvm_release_faultin_page. This makes little sense for two reasons: first, because the function sets up the private data for the page and the return value feels like it has been bolted on the side; second, because what really matters is whether the _shadow_ TLB entry is writable. If it is not writable, the page can be released as non-dirty. Shift from using tlbe_is_writable(gtlbe) to doing the same check on the shadow TLB entry.

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 reStructuredText 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.
