Does Mach ignore the Multiboot(1 or 2) information data structure?

[Paul Dufresne]

Well, I was to say that I took a quick look to GNU Mach code, and that it seems 
to just ignore the Multiboot2 information data structure,
but it is probably normal, as it use Multiboot "1" Magic: 
line 18 of 
http://git.savannah.gnu.org/cgit/hurd/gnumach.git/tree/i386/i386at/boothdr.S
#define MULTIBOOT_MAGIC         0x1BADB002

https://en.wikipedia.org/wiki/Multiboot_specification says:
"Within the OS image file, the header must be in the first 8192 (2¹³) bytes for 
Multiboot and 32768 (2¹⁵) bytes for Multiboot2. The loader searches for a magic 
number to find the header, which is 0x1BADB002 for Multiboot and 0xE85250D6 for 
Multiboot2."

Still, later on that page: "Before jumping to the OS entry point, the boot 
loader must provide a boot information structure to tell the OS how it left the 
system; for Multiboot, this is a struct, and for Multiboot2, every field 
(group) has a type tag and a size. "
Maybe I did not search enough, but I did not found that struct in the code yet.

So GNU Mach code probably need some refreshment toward using Multiboot2... and 
save the information data structure somewhere.

Or I missed something?
