 * Helper macros to support writing architecture specific

 * A minimal linker scripts has following content:
 * [This is a sample, architectures may have special requiriements]
 *
 * OUTPUT_FORMAT(...)
 * OUTPUT_ARCH(...)
 * ENTRY(...)
 * SECTIONS
 * {
 *	. = START;
 *	__init_begin = .;
 *	HEAD_TEXT_SECTION
 *	INIT_TEXT_SECTION(PAGE_SIZE)
 *	INIT_DATA_SECTION(...)
 *	PERCPU(PAGE_SIZE)

 *	_end = .;
 *
 *	STABS_DEBUG
 *	DWARF_DEBUG
 *
 *	DISCARDS		// must be the last
 * }
 *
 * [__init_begin, __init_end] is the init section that may be freed after init
 * [_stext, _etext] is the text section
 * [_sdata, _edata] is the data section
 *
 * Some of the included output section have their own set of constants.
 * Examples are: [__initramfs_start, __initramfs_end] for initramfs and
 *               [__nosave_begin, __nosave_end] for the nosave data
