powerpc: hard_irq_disable(): Call trace_hardirqs_off after disabling
lockdep.c has this:
/*
* So we're supposed to get called after you mask local IRQs,
* but for some reason the hardware doesn't quite think you did
* a proper job.
*/
if (DEBUG_LOCKS_WARN_ON(!irqs_disabled()))
return;
Since irqs_disabled() is based on soft_enabled(), that (not just the
hard EE bit) needs to be 0 before we call trace_hardirqs_off.
