I did not, although I just read it.

I have a hard time seeing maintaining backwards/forwards compatibility
as "very wrong" ... it would seem like a pretty major concern.  In
comparison losing the currently nonexistent /sys file seems like a
rather minor issue.

My suggestion would be to have a universal parser for reboot= and have
the arch functions fed data in already parsed form.

You have to ask the arm and unicore32 maintainers that, obviously.

reboot_cpu=<n>
