Do these special kernel sections include things like the parisc .text.do_softirq, .text.sys_exit, etc? James raised a good objection to the parisc patch of this series. I'm guessing most people saw it already but I'll paste it here for reference, This would destroy all of the named parisc text ordering we do above the removed line because now you'd have swept up all the function sections before we get to them, won't it? The ordering is an execution speed up on 32 bit systems because our relative jump is so short. James Will you changes handle this OK? -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
