Hello,
I've had problems buidling kexec-tools with pretty old (but currently
official in "enterprise" distributions....) kernels, namely a 3.10.x
series in the scope of a buildroot image generation.
It boils down to being due to missing VIDEO_CAPABILITY_64BIT_BASE
define (that appeared from 4.4.x kernels it seems in screen_info.h) in
kexec/arch/i386/x86-linux-setup.c from
a98b4da4fd4f1c7ad9a47ade17f377b833e5c9ae.
The local fix could be trivial, something like:
diff --git a/package/kexec/0003-kexec-tools-video-capability-64bit-define.patch
b/package/kexec/0003-kexec-tools-video-capability-64bit-define.patch

But I was wondering if this is something that would get considered or
dropped, and better managed at buildroot or so level, given the very
old version we are talking about.
Many thanks,
Federico
