1570 help
1571 SMTC pseudo-interrupts between TCs are deferred and queued
1572 if the target TC is interrupt-inhibited (IXMT). In the first
1573 SMTC prototypes, these queued IPIs were serviced on return
1574 to user mode, or on entry into the kernel idle loop. The
1575 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1576 processing, which adds runtime overhead (hence the option to turn
1577 it off), but ensures that IPIs are handled promptly even under
1578 heavy I/O interrupt load.

1970 developed as an open alternative to the IBM MicroChannel bus.
1971
1972 The EISA bus provided some of the features of the IBM MicroChannel
1973 bus while maintaining backward compatibility with cards made for
1974 the older ISA bus. The EISA bus saw limited use between 1988 and
1975 1995 when it was made obsolete by the PCI bus.
1976
1977 Say Y here if you are building a kernel for an EISA-based machine.
1978
1979 Otherwise, say N.

2020 A 64-bit kernel is usually built using the 64-bit ELF binary object
2021 format as it's one that allows arbitrary 64-bit constructs. For
2022 kernels that are loaded within the KSEG compatibility segments the
2023 32-bit ELF format can optionally be used resulting in a somewhat
2024 smaller binary, but this option is not explicitly supported by the
2025 toolchain and since binutils 2.14 it does not even work at all.
2026
2027 Say Y to use the 64-bit format or N to use the 32-bit one.

2029 If unsure say Y.
