[POWERPC] Make soft_enabled irqs preempt safe Rewrite local_get_flags and local_irq_disable to use r13 explicitly, to avoid the risk that gcc will split get_paca()->soft_enabled into a sequence unsafe against preemption. Similar care in local_irq_restore. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
