1052 Please make sure to pick the right CPU type. Linux/MIPS is not
1053 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1054 *not* work on R4000 machines and vice versa. However, since most
1055 of the supported machines have an R4000 (or similar) CPU, R4x00
1056 might be a safe bet. If the resulting kernel does not work,
1057 try to recompile with R3000.

1466 SMTC pseudo-interrupts between TCs are deferred and queued
1467 if the target TC is interrupt-inhibited (IXMT). In the first
1468 SMTC prototypes, these queued IPIs were serviced on return
1469 to user mode, or on entry into the kernel idle loop. The
1470 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1471 processing, which adds runtime overhead (hence the option to turn
1472 it off), but ensures that IPIs are handled promptly even under
1473 heavy I/O interrupt load.

1552 SmartMIPS is a extension of the MIPS32 architecture aimed at
1553 increased security at both hardware and software level for
1554 smartcards. Enabling this option will allow proper use of the
1555 SmartMIPS instructions by Linux applications. However a kernel with
1556 this option will not work on a MIPS core without SmartMIPS core. If
