This series adds support for the ARMv8.3 pointer authentication
extension. The series contains Mark's original patches to enable pointer
authentication for userspace [1], followed by early RFC patches using
pointer authentication in the kernel.
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. :)
