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. -- Hollis Blanchard IBM Linux Technology Center -- To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
