It wasn't obvious to me where the PAC mismatch exceptions will be
caught. I'm mainly curious to compare the PAC exception handling to
the existing stack-protector panic(). Can you point me to which
routines manage that? (Perhaps I just missed it in the series...)

Thanks for the series! I'm quite excited for ARMv8.3 hardware. :)
