1017 might be a safe bet. If the resulting kernel does not work,

1412 SMTC pseudo-interrupts between TCs are deferred and queued
1413 if the target TC is interrupt-inhibited (IXMT). In the first
1414 SMTC prototypes, these queued IPIs were serviced on return
1415 to user mode, or on entry into the kernel idle loop. The
1416 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1417 processing, which adds runtime overhead (hence the option to turn
1418 it off), but ensures that IPIs are handled promptly even under

1879 A 64-bit kernel is usually built using the 64-bit ELF binary object
1880 format as it's one that allows arbitrary 64-bit constructs. For
1881 kernels that are loaded within the KSEG compatibility segments the
1882 32-bit ELF format can optionally be used resulting in a somewhat
1883 smaller binary, but this option is not explicitly supported by the
1884 toolchain and since binutils 2.14 it does not even work at all.
1885
1886 Say Y to use the 64-bit format or N to use the 32-bit one.
1887
1888 If unsure say Y.

1898 Select this option if you want Linux/MIPS 32-bit binary
1899 compatibility. Since all software available for Linux/MIPS is
1900 currently 32-bit you should say Y here.

1916 Select this option if you want to run o32 binaries. These are pure
1917 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of

1927 64-bit binaries using 32-bit quantities for addressing and certain
1928 data that would normally be 64-bit. They are used in special
