1053 Please make sure to pick the right CPU type. Linux/MIPS is not
1054 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1055 *not* work on R4000 machines and vice versa. However, since most
1056 of the supported machines have an R4000 (or similar) CPU, R4x00
1057 might be a safe bet. If the resulting kernel does not work,
1058 try to recompile with R3000.

1467 SMTC pseudo-interrupts between TCs are deferred and queued
1468 if the target TC is interrupt-inhibited (IXMT). In the first
1469 SMTC prototypes, these queued IPIs were serviced on return
1470 to user mode, or on entry into the kernel idle loop. The
1471 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1472 processing, which adds runtime overhead (hence the option to turn
1473 it off), but ensures that IPIs are handled promptly even under
1474 heavy I/O interrupt load.

1553 SmartMIPS is a extension of the MIPS32 architecture aimed at
1554 increased security at both hardware and software level for
1555 smartcards. Enabling this option will allow proper use of the
1556 SmartMIPS instructions by Linux applications. However a kernel with
1557 this option will not work on a MIPS core without SmartMIPS core. If

1923 The EISA bus provided some of the features of the IBM MicroChannel
1924 bus while maintaining backward compatibility with cards made for
1925 the older ISA bus. The EISA bus saw limited use between 1988 and
1926 1995 when it was made obsolete by the PCI bus.
1927
1928 Say Y here if you are building a kernel for an EISA-based machine.
1929
1930 Otherwise, say N.
