Yes, you said that this is a boot/compressed stage -> kernel proper info
pass field but let's document it anyway, please, and say what it is,
just like:
1E4/004 ALL scratch Scratch field for the kernel setup code
is documented, for example.
And now that I look at it, acpi_rsdp_addr isn't documented either so if
you wanna add it too, while you're at it, that would be nice.
Thx.
