Sorry for not noticing this earlier but this has nothing to do with the
remaining part of the patch.
To be able to set this flag, you need to mark timer & perf interrupts.
If you already use IRQF_TIMER for the timer and perf interrupts are
already coming as NMU then you are done. But please split this out as a
separate patch.
