I think you're referring to kvmppc_mmu_invalidate() and
kvmppc_mmu_priv_switch(). I had the locking in there because I thought
that it was needed around kvmppc_44x_shadow_release() (which ends up
becoming put_page()). However, judging from the x86 code I don't think
that's accurate, so I should remove that locking.
