General informations

The Linux kernel configuration item CONFIG_X86_X32 has multiple definitions:

x32 ABI for 64-bit mode (EXPERIMENTAL) found in arch/x86/Kconfig

The configuration item CONFIG_X86_X32:

Help text

Include code to run binaries for the x32 native 32-bit ABI for 64-bit processors. An x32 process gets access to the full 64-bit register file and wide data path while leaving pointers at 32 bits for smaller memory footprint.

You will need a recent binutils (2.22 or later) with elf32_x86_64 support enabled to compile a kernel with this option set.
