996 Please make sure to pick the right CPU type. Linux/MIPS is not
997 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
998 *not* work on R4000 machines and vice versa. However, since most
999 of the supported machines have an R4000 (or similar) CPU, R4x00
1000 might be a safe bet. If the resulting kernel does not work,
1001 try to recompile with R3000.

1409 SMTC pseudo-interrupts between TCs are deferred and queued
1410 if the target TC is interrupt-inhibited (IXMT). In the first
1411 SMTC prototypes, these queued IPIs were serviced on return
1412 to user mode, or on entry into the kernel idle loop. The
1413 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1414 processing, which adds runtime overhead (hence the option to turn
1415 it off), but ensures that IPIs are handled promptly even under
1416 heavy I/O interrupt load.

1917 Select this option if you want Linux/MIPS 32-bit binary
1918 compatibility. Since all software available for Linux/MIPS is
1919 currently 32-bit you should say Y here.

1935 Select this option if you want to run o32 binaries. These are pure
1936 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1937 existing binaries are in this format.

1946 64-bit binaries using 32-bit quantities for addressing and certain
