Hi Christian,
This adds the guest portion of the hypercall infrastructure, basically an
illegal instruction with a defined layout.
See http://kvm.qumranet.com/kvmwiki/PowerPC_Hypercall_ABI for more detail
on the hypercall ABI for powerpc.

Ummm didn't you add this in patch 2 of 6?
This is just because I initially wanted to split Host & Guest patch series.
I need to separate my patches a bit more anyway for the next submission thanks for pointing out this duplication.
