This is an ABI structure rather than some purely kernel construct, right?
I searched through all of the specs to which you linked in the cover
letter. I looked for "blob", "guid", the magic and part of the GUID
itself trying to find where this is defined to see if the struct is correct.
I couldn't find anything.
Where is the spec for this blob? How large is it? Did you mean to
leave a 4-byte hole after secrets_len and before cpuid_phys?
