1037 Please make sure to pick the right CPU type. Linux/MIPS is not
1038 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1039 *not* work on R4000 machines and vice versa. However, since most
1040 of the supported machines have an R4000 (or similar) CPU, R4x00
1041 might be a safe bet. If the resulting kernel does not work,
1042 try to recompile with R3000.

1464 SMTC pseudo-interrupts between TCs are deferred and queued
1465 if the target TC is interrupt-inhibited (IXMT). In the first
1466 SMTC prototypes, these queued IPIs were serviced on return
1467 to user mode, or on entry into the kernel idle loop. The
1468 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1469 processing, which adds runtime overhead (hence the option to turn

1986 currently 32-bit you should say Y here.

2002 Select this option if you want to run o32 binaries. These are pure
2003 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
2004 existing binaries are in this format.

2013 64-bit binaries using 32-bit quantities for addressing and certain
