I was about to go an fix SPARC but then looked in the tree for actual users, and I see one, and only one, in the lockdep code which tries to grab the tasklist_lock. That's it (well.. there's one strange IA64 specific case in the MCA code too). You say you were fixing up PARISC and actually hit this problem, was it exactly this lockdep case? I really doubt it... - To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
