54 The Extended Industry Standard Architecture (EISA) bus was
55 developed as an open alternative to the IBM MicroChannel bus.
56
57 The EISA bus provided some of the features of the IBM MicroChannel
58 bus while maintaining backward compatibility with cards made for
59 the older ISA bus. The EISA bus saw limited use between 1988 and
60 1995 when it was made obsolete by the PCI bus.

722 help
723 This option allows for the kernel to be compiled using the latest
724 ARM ABI (aka EABI). This is only useful if you are using a user
725 space environment that is also compiled with EABI.
726
727 Since there are major incompatibilities between the legacy ABI and
728 EABI, especially with regard to structure member alignment, this
729 option also changes the kernel syscall calling convention to
730 disambiguate both ABIs and allow for backward compatibility support
731 (selected with CONFIG_OABI_COMPAT).
732
733 To use this you need GCC version 4.0.0 or later.

740 This option preserves the old syscall interface along with the
741 new (ARM EABI) one. It also provides a compatibility layer to
742 intercept syscalls that have structure arguments which layout
743 in memory differs between the legacy ABI and the new ARM EABI
744 (only for non "thumb" binaries). This option adds a tiny
745 overhead to all syscalls and produces a slightly larger kernel.
746 If you know you'll be using only pure EABI user space then you
747 can say N here. If this option is not selected and you attempt
748 to execute a legacy ABI binary then the result will be
749 UNPREDICTABLE (in fact it can be predicted that it won't work
