534 Qemu is a software emulator which among other architectures also
535 can simulate a MIPS32 4Kc system. This patch adds support for the
536 system architecture that currently is being simulated by Qemu. It
537 will eventually be removed again when Qemu has the capability to
538 simulate actual MIPS hardware platforms. More information on Qemu

1617 The EISA bus provided some of the features of the IBM MicroChannel
1618 bus while maintaining backward compatibility with cards made for
1619 the older ISA bus. The EISA bus saw limited use between 1988 and
1620 1995 when it was made obsolete by the PCI bus.
1621
1622 Say Y here if you are building a kernel for an EISA-based machine.
1623
1624 Otherwise, say N.

1668 help
1669 A 64-bit kernel is usually built using the 64-bit ELF binary object
1670 format as it's one that allows arbitrary 64-bit constructs. For
1671 kernels that are loaded within the KSEG compatibility segments the
1672 32-bit ELF format can optionally be used resulting in a somewhat
1673 smaller binary, but this option is not explicitly supported by the
1674 toolchain and since binutils 2.14 it does not even work at all.
1675
1676 Say Y to use the 64-bit format or N to use the 32-bit one.
1677
1678 If unsure say Y.
