1014 Please make sure to pick the right CPU type. Linux/MIPS is not
1015 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1016 *not* work on R4000 machines and vice versa. However, since most
1017 of the supported machines have an R4000 (or similar) CPU, R4x00
1018 might be a safe bet. If the resulting kernel does not work,
1019 try to recompile with R3000.

1441 SMTC pseudo-interrupts between TCs are deferred and queued
1442 if the target TC is interrupt-inhibited (IXMT). In the first
1443 SMTC prototypes, these queued IPIs were serviced on return
1444 to user mode, or on entry into the kernel idle loop. The
1445 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1446 processing, which adds runtime overhead (hence the option to turn
