Right now powerpc provides an implementation to read elf files
with the kexec_file() syscall. Make that available as a public
kexec interface so it can be re-used on other architectures.

Why are you persisting at not using -C when creating your patch ? Do you
want to hide the changes you did while copying
arch/powerpc/kernel/kexec_elf_64.c to kernel/kexec_elf.c ?
Or you want to make life harder for the reviewers ?

Sorry, never used -C before. I used:

git send-email --annotate -v2 -7 --to kexec@lists.infradead.org --cc deller@gmx.de,linuxppc-dev@lists.ozlabs.org -v --format-patch -C -M

However, it looks like it only works when started this way:

git send-email --format-patch -M -C --annotate -v2 -7 --to kexec@lists.infradead.org --cc deller@gmx.de,linuxppc-dev@lists.ozlabs.org -v

I'll resend v2.

Best Regards,
Sven
