The pseries machine type is a bit unusual in that it runs a paravirtualized guest. The guest expects to interact with a hypervisor, and qemu emulates the functions of that hypervisor directly, rather than executing hypervisor code within the emulated system. To implement this in TCG, we need to intercept hypercall instructions and direct them to the machine's hypercall handlers, rather than attempting to perform a privilege change within TCG. This is controlled by a global hook - cpu_ppc_hypercall. This cleanup makes the handling a little cleaner and more extensible than a single global variable. Instead, each CPU to have hypercalls intercepted has a pointer set to a QOM object implementing a new virtual hypervisor interface. A method in that interface is called by TCG when it sees a hypercall instruction. It's possible we may want to add other methods in future.
