If MMIO emulation fails we don't want to crash the whole guest by returning to userspace. The original commitbbf45ba57e("KVM: ppc: PowerPC 440 KVM implementation") added a todo: /* XXX Deliver Program interrupt to guest. */ and later the commitd69614a295("KVM: PPC: Separate loadstore emulation from priv emulation") added the Program interrupt injection but in another file, so I'm assuming it was missed that this block needed to be altered. Also change the message to a ratelimited one since we're letting the guest run and it could flood the host logs.

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.
