No, since it has been removed from the latest Principles of Operation
too.

See "Summary of Changes in Fifteenth Edition": "Since support for the
crypto facility has been deprecated for multiple machine genera-
tions, the definition for the crypto-operation exception has been
removed."

We never supported that exception in Linux, since our exception
handler masks the interruption code with 0x7f, which would remove that
bit anyway. I don't know what "multiple machine generations" above
means, but I guess this translates probably to decades :)
