Does the tiny kexec kernel actually need network, bio(4) or HID devices? octeon/BOOT does not have any of this.
Looks like too much of powerpc64/RAMDISK remained, but I might be missing some obvious difference between these platforms. The Raptor CS Blackbird used for the re-upgrade prevention diff still boots with this smaller config. I'm just curious, this diff shows what I mean and doesn't fix anything.
