+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.

+config OABI_COMPAT
+	bool "Allow old ABI binaries to run with this kernel"

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

+ * The legacy ABI and the new ARM EABI have different rules making some

+ * Most notably, Eabi says 64-bit members should be 64-bit aligned instead of
+ * simply word aligned.  EABI also pads structures to the size of the largest
+ * member it contains instead of the invariant 32-bit.
+ *
+ * The following syscalls are affected:
+ *
+ * sys_stat64:
+ * sys_lstat64:
+ * sys_fstat64:
+ *
+ *   struct stat64 has different sizes and some members are shifted
+ *   Compatibility wrappers are needed for them and provided below.
+ *
+ * sys_fcntl64:
+ *
+ *   struct flock64 has different sizes and some members are shifted
+ *   A compatibility wrapper is needed and provided below.
+ *
+ * sys_statfs64:
+ * sys_fstatfs64:
+ *
+ *   struct statfs64 has extra padding with EABI growing its size from
+ *   84 to 88.  This struct is now __attribute__((packed,aligned(4)))
+ *   with a small assembly wrapper to force the sz argument to 84 if it is 88
+ *   to avoid copying the extra padding over user space unexpecting it.
+ *
+ * sys_newuname:
+ *
+ *   struct new_utsname has no padding with EABI.  No problem there.
+ *
+ * sys_epoll_ctl:
+ * sys_epoll_wait:
+ *
+ *   struct epoll_event has its second member shifted also affecting the
+ *   structure size. Compatibility wrappers are needed and provided below.
+ *
+ * sys_ipc:
+ * sys_semop:
+ * sys_semtimedop:
+ *
+ *   struct sembuf loses its padding with EABI.  Since arrays of them are
