[MIPS] lockdep: Deal with interrupt disable hazard in TRACE_IRQFLAGS Between the mtc0 or di instruction that disables interrupts and the following hazard barrier a processor may still take interrupts. If an interrupt is taken after interrupts are disabled but before the state is updated it will appear to restore_all that it is incorrectly returning with interrupts disabled.
