Some coming changes, namely the integration of bhyve, require access to a vector for performing IPIs.  Allocating a new vector is one option, but without a corresponding interface for deallocation, that course of action is unattractive.  Alternatively, accessing the already-allocated IPI vector for poke_cpu() would be perfectly adequate.  Since that data is private to pcplusmp and apix, a function to access it would be preferable to hacking up a direct external reference.  To that end, I propose adding a psm_cached_ipivect interface to psm_ops which would allow such access.
