      [MIPS] SMTC: Instant IPI replay. · ac8be955
      Ralf Baechle authored
      SMTC pseudo-interrupts between TCs are deferred and queued if the target
      TC is interrupt-inhibited (IXMT). In the first SMTC prototypes, these
      queued IPIs were serviced on return to user mode, or on entry into the
      kernel idle loop. The INSTANT_REPLAY option dispatches them as part of
      local_irq_restore() processing, which adds runtime overhead (hence the
      option to turn it off), but ensures that IPIs are handled promptly even
      under heavy I/O interrupt load.
