x86_64 platform : addresses type
...32 bits, such as in
typedef struct {
u32 flags;
u32 mem_lower;
u32 mem_upper;
u32 boot_device;
u32 cmdline;
u32 mods_count;
u32 mods_addr;
union {
aout_symbol_table_t aout_sym;
elf_section_header_table_t elf_sec;
} u;
u32 mmap_length;
u32 mmap_addr;
} multiboot_info_t
However, on x86_64 using gcc, addresses as well as unsigned long are 64
bits long.
It seems that luckily mmap_addr is below 2*32-1, making the u32 type
acceptable
so far (for instance in function __start_xen, where the memory map is
turned into
another structure) but what...

[PATCH] Increasing E820MAX
We found machines with >32 E820 memory map entries, where Xen fails to
boot (but Linux does boot fine). The native Linux (both x86 and x86_86)
already has:
#define E820MAX 128 /* number of entries in E820MAP */
