If not, can this be pulled into 4.5? How is that 4.5 material? Does it fix an observable bug or a regression from a previous?

Are we just waiting for Rafael to make the final call then? -Loc -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
