1411 SMTC pseudo-interrupts between TCs are deferred and queued
1412 if the target TC is interrupt-inhibited (IXMT). In the first
1413 SMTC prototypes, these queued IPIs were serviced on return
1414 to user mode, or on entry into the kernel idle loop. The
1415 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1416 processing, which adds runtime overhead (hence the option to turn

1877 help
1878 A 64-bit kernel is usually built using the 64-bit ELF binary object
1879 format as it's one that allows arbitrary 64-bit constructs. For
1880 kernels that are loaded within the KSEG compatibility segments the
1881 32-bit ELF format can optionally be used resulting in a somewhat
1882 smaller binary, but this option is not explicitly supported by the
1883 toolchain and since binutils 2.14 it does not even work at all.
1884
1885 Say Y to use the 64-bit format or N to use the 32-bit one.
1886
1887 If unsure say Y.

1897 Select this option if you want Linux/MIPS 32-bit binary
1898 compatibility. Since all software available for Linux/MIPS is
1899 currently 32-bit you should say Y here.

1915 Select this option if you want to run o32 binaries. These are pure
1916 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1917 existing binaries are in this format.
1918
1919 If unsure, say Y.

1925 Select this option if you want to run n32 binaries. These are
1926 64-bit binaries using 32-bit quantities for addressing and certain
1927 data that would normally be 64-bit. They are used in special
1928 cases.
