1575 help
1576 SMTC pseudo-interrupts between TCs are deferred and queued
1577 if the target TC is interrupt-inhibited (IXMT). In the first
1578 SMTC prototypes, these queued IPIs were serviced on return
1579 to user mode, or on entry into the kernel idle loop. The
1580 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1581 processing, which adds runtime overhead (hence the option to turn
1582 it off), but ensures that IPIs are handled promptly even under
1583 heavy I/O interrupt load.
