Thanks for finishing this one off as well! I don't know if you did this as a
reaction to me doing the same for the three other platforms that don't
use GENERIC_IRQ_MULTI_HANDLER yet[1], or if this was just a lucky
coincidence. It sounds like this should be part of Ard's IRQ stack series
as well then (adding him to Cc), as it fits in with my patches there.

Would you mind also implementing and testing the missing bits
for the stack switching on nommu irq entry, corresponding to [2] so
we can just use that part unconditionally as well?
