commit 96a13f57b946be7a6c10405e4bd780c0b6b6fe63 upstream.
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.
