While trying to squash them in I realized that things become very ugly 
here. If we have to explicitly #ifdef the generators, why don't we just 
call a new macro for the SPRN_G access and #ifdef on CONFIG_KVM_BOOKE_HV?

#ifdef CONFIG_KVM_BOOKE_HV
SPRNG_WRAPPER(sprg0, SPRN_GSPRG0)
...
#else
SHARED_WRAPPER(sprg0, SPRN_GSPRG0)
#endif

that way the code flow is at least reasonably obvious :). I'll remove 
the patches from my queue for now.
