424 This option preserves the old syscall interface along with the
425 new (ARM EABI) one. It also provides a compatibility layer to
426 intercept syscalls that have structure arguments which layout
427 in memory differs between the legacy ABI and the new ARM EABI
428 (only for non "thumb" binaries). This option adds a tiny
429 overhead to all syscalls and produces a slightly larger kernel.
430 If you know you'll be using only pure EABI user space then you
431 can say N here. If this option is not selected and you attempt
432 to execute a legacy ABI binary then the result will be
433 UNPREDICTABLE (in fact it can be predicted that it won't work
434 at all). If in doubt say Y.
