+config AEABI
+        bool "Use the ARM EABI to compile the kernel"
+        help
+          This option allows for the kernel to be compiled using the latest
+          ARM ABI (aka EABI).  This is only useful if you are using a user
+          space environment that is also compiled with EABI.
+
+          Since there are major incompatibilities between the legacy ABI and
+          EABI, especially with regard to structure member alignment, this
+          option also changes the kernel syscall calling convention to
+          disambiguate both ABIs and allow for backward compatibility support
+          (selected with CONFIG_OABI_COMPAT).
+
+          To use this you need GCC version 4.0.0 or later.
