You know, I had thought this was unnecessary, and I was going to remove it. However, it looks like the 440 must invalidate the icache any time an (executable) translation changes. Technically we could handle this like the kernel does with icache_44x_need_flush, but I don't think we're losing much by just leaving this ifdef here. -- Hollis Blanchard IBM Linux Technology Center -- To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
