* stage2/boot.c (linux_mem_size): New variable.
	(load_image): Check a mem= option and set LINUX_MEM_SIZE to the
	specified memory size, if any. Otherwise, to zero. When an
	overflow is detected, use LINUX_INITRD_MAX_ADDRESS instead.
	(load_initrd): If LINUX_MEM_SIZE is non-zero, use it instead of
	the actual memory size.
	* stage2/char_io.c (safe_parse_maxint): Use ERR_NUMBER_OVERFLOW
	instead of ERR_NUMBER_PARSING, when an overflow occurs.
	* stage2/common.c [!STAGE1_5] (err_list): Added
	ERR_NUMBER_OVERFLOW.
	* stage2/shared.h (ERR_NUMBER_OVERFLOW): New constant.
