I realize there's no SMP 8xx, and this is only called in place of steal_context_up(), but in case others think of reusing this elsewhere[1]... -Scott [1] It might be helpful on e500 derivatives in virtualized environments where invalidate-by-PID is expensive, depending on how often stealing happens there. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
