[Buildroot] [PATCH 1/1] package/kexec: fix build on pre 4.4 kernels

[Federico Pellegrin]

Hi Thomas,
Just wanted to revive this thread/patch even if not with very useful
info: pinged a few times in kexec mailing list but nothing yet, just
one partecipant kindly forwarded directly also to the developer that
wrote the specific code, but then everything stopped still sadly (~3
week now since first patch post).

For the time being we keep it as a local patch, I'm not sure how you
proceed in buildroot in such cases.

Cheers,
Federico
