Andreas Gruenbacher 11dc8286f9 powerpc/kvm: Fix kvm_use_magic_page
commit 0c8eb2884a42d992c7726539328b7d3568f22143 upstream.

When switching from __get_user to fault_in_pages_readable, commit
9f9eae5ce7 broke kvm_use_magic_page: like __get_user,
fault_in_pages_readable returns 0 on success.

Fixes: 9f9eae5ce7 ("powerpc/kvm: Prefer fault_in_pages_readable function")

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.
