For QEMU, the majority of the work in enabling instruction interpretation
is handled via new VFIO ioctls to SET the appropriate interpretation and
interrupt forwarding modes, and to GET the function handle to use for
interpretive execution.

This series implements these new ioctls, as well as adding a new, optional
'intercept' parameter to zpci to request interpretation support not be used
as well as an 'intassist' parameter to determine whether or not the
firmware assist will be used for interrupt delivery or whether the host
will be responsible for delivering all interrupts.

 Hi Matthew,

would it make sense to create a docs/system/s390x/zpci.rst doc file, too, where you could describe such new parameters like 'intassist' and 'intercept' (or is it 'interp') ? ... otherwise hardly anybody except you will know how to use these parameters later...
