   * Usage guidelines:
   * _text, _data: architecture specific, don't use them in arch-independent code
   * [_stext, _etext]: contains .text.* sections, may also contain .rodata.*
   *                   and/or .init.* sections
   * [_sdata, _edata]: contains .data.* sections, may also contain .rodata.*
   *                   and/or .init.* sections.
   * [__start_rodata, __end_rodata]: contains .rodata.* sections
   * [__init_begin, __init_end]: contains .init.* sections, but .init.text.*
   *                   may be out of this range on some architectures.
   * [_sinittext, _einittext]: contains .init.text.* sections
   * [__bss_start, __bss_stop]: contains BSS sections
   *
   * Following global variables are optional and may be unavailable on some
   * architectures and/or kernel configurations.
