 7 * Usage guidelines:
 8 * _text, _data: architecture specific, don't use them in arch-independent code
 9 * [_stext, _etext]: contains .text.* sections, may also contain .rodata.*
10 *                   and/or .init.* sections
11 * [_sdata, _edata]: contains .data.* sections, may also contain .rodata.*
12 *                   and/or .init.* sections.
13 * [__start_rodata, __end_rodata]: contains .rodata.* sections
14 * [__init_begin, __init_end]: contains .init.* sections, but .init.text.*
15 *                   may be out of this range on some architectures.
16 * [_sinittext, _einittext]: contains .init.text.* sections
17 * [__bss_start, __bss_stop]: contains BSS sections
18 *
19 * Following global variables are optional and may be unavailable on some
20 * architectures and/or kernel configurations.
