this is a second part usable without switching on protection key stuff.
- added XEN_IA64_NPKRS
- added IA64_INST_KEY_MISS_VECTOR and IA64_DATA_KEY_MISS_VECTOR
to ia64_handle_reflection
- the key is now used during handling XEN_IA64_OPTF_IDENT_MAP_REG7.

I tested with booting domU PV linux.
Please have a look and send comments.
Thanks.

Dietmar.
