Although we merged support for pseudo-nmi using interrupt priority
masking in 5.1, we've since uncovered a number of non-trivial issues
with the implementation. Although there are patches pending to address
these problems, we're facing issues that prevent us from merging them at
this current time:

For now, simply mark this optional feature as BROKEN in the hope that we
can fix things properly in the near future.
