We are declaring the dummy section (used to work around a binutils bug) as PT_NOTE, but we don't have enough bytes for it to be a valid note header, and kexec userspace complains: Warning: Elf Note name is not null terminated Warning: append= option is not passed. Using the first kernel root partition Warning: Elf Note name is not null terminated Instead of using the arbitray value 0xf177 (aka "fill"), declare a no-name no-description note of type 0. Signed-off-by: Milton Miller <miltonm@bga.com> --- verified on binutils-2.6.17 that the workaround still works (that is we get a phdr that does not have all zeros in the paddr field, and a relocatable kernel booted).
