Subject: [PATCH] [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.
