Hi all,

This series is a follow-up on [1], which tried to address the
remaining missing HCR_EL2.TIDx traps. I've hopefully now adressed the
comments that Peter and Edgar raised.

I've also tried to tackle missing traps generated by HSTR_EL2, which
got completely ignored so far. Note that this results in the use of a
new TB bit, which I understand is a rare resource. I'd welcome
comments on how to handle it differently if at all possible.

Finally, and as a bonus non-feature, I've added support for the
missing Jazelle registers, giving me the opportunity to allow trapping
of JIDR to EL2 using HCR_EL2.TID0. Yay, Christmas! ;-)

I'm now going back to kernel stuff. I swear!

To save you from having to roll a v3, I've fixed up the
handful of nits Richard and I found as I applied this
series to target-arm.next.

Ah, brilliant. Thanks a lot Peter.

Jazz is not dead. It just smells funny...
