    Pull x32 support for x86-64 from Ingo Molnar:
     "This tree introduces the X32 binary format and execution mode for x86:
      32-bit data space binaries using 64-bit instructions and 64-bit kernel
      This allows applications whose working set fits into a 32 bits address
      space to make use of 64-bit instructions while using a 32-bit address
      space with shorter pointers, more compressed data structures, etc."
    Fix up trivial context conflicts in arch/x86/{Kconfig,vdso/vma.c}
