The main this is that since this is a fixed-format, ABI-defined
structure, regardless of individual fields it should be exported as a
binary object. That is also the only way to deal with a kernel which
may not itself know about specific items making the data available to
other users, like kexec.
It's not clear to me from reading the code what model you're using for
exporting this data in sysfs. Could you describe it in some detail?
What I had envisioned would be an object for the boot_params structure
and a systematic object for each linked-list object, at a very minimum.
