[PATCH 2/5] xen/xsm: Complete altcall conversion of xsm interface

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

With alternative_call() capable of handling compound types, the three
remaining hooks can be optimised at boot time too.

I'm on the fence as to whether to declare this as fixing "xsm: convert xsm_ops
hook calls to alternative call"
