You can put code into P2 space today on Itanium.  Fully supported.  Just link with /SEGMENT=CODE=P2.  The compilers don't care.  The generated code is the same.

Personally, I'd like to see that be the default in the future.  No sense cluttering up your P0 space with code especially if you have data structures that are still 32-bit address dependent.
