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: https://lkml.kernel.org/r/1556553607-46531-1-git-send-email-julien.thierry@arm.com For now, simply mark this optional feature as BROKEN in the hope that we can fix things properly in the near future.
