So if we do need to check this, we should check it here. If we don't,
then we can drop these patches.

Historically other things would break in nasty ways if you tried
to do crypto in hard IRQ contexts, e.g., overwritten kmap slots
back when we had individual slots for each context, but I don't
think we've ever found anyone crazy enough to do that to warrant
a run-time check.

I'd just leave it out for now.

Fair enough. Would you like me to resend the series with these patches
left out Or are you ok to just take the remaining ones (assuming there
are no issues reported with those)?
