63 The Extended Industry Standard Architecture (EISA) bus was
64 developed as an open alternative to the IBM MicroChannel bus.
65
66 The EISA bus provided some of the features of the IBM MicroChannel
67 bus while maintaining backward compatibility with cards made for
68 the older ISA bus. The EISA bus saw limited use between 1988 and
69 1995 when it was made obsolete by the PCI bus.

756 This option enables the workaround for the 430973 Cortex-A8
757 (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb
758 interworking branch is replaced with another code sequence at the
759 same virtual address, whether due to self-modifying code or virtual
760 to physical address re-mapping, Cortex-A8 does not recover from the
761 stale interworking branch prediction. This results in Cortex-A8
762 executing the new code sequence in the incorrect ARM or Thumb state.
763 The workaround enables the BTB/BTAC operations by setting ACTLR.IBE
764 and also flushes the branch target cache at every context switch.
765 Note that setting specific bits in the ACTLR register may not be
766 available in non-secure mode.

941 This option preserves the old syscall interface along with the
942 new (ARM EABI) one. It also provides a compatibility layer to
943 intercept syscalls that have structure arguments which layout
944 in memory differs between the legacy ABI and the new ARM EABI
945 (only for non "thumb" binaries). This option adds a tiny
946 overhead to all syscalls and produces a slightly larger kernel.
947 If you know you'll be using only pure EABI user space then you
948 can say N here. If this option is not selected and you attempt
949 to execute a legacy ABI binary then the result will be
