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

[Yann E. MORIN]

Federico, All,

On 2021-02-03 11:09 +0100, Federico Pellegrin spake thusly:
> kexec build will fail on older kernels (pre 4.4) as the define VIDEO_CAPABILITY_64BIT_BASE was not present at that time.
> 
> This patch adds it, as per linux/include/uapi/linux/screen_info.h, if not present.
> 
> Signed-off-by: Federico Pellegrin <fede at evolware.org>

This patch is no longer needed now that we updated kexec to 2.0.21, then
2.0.22.

Sorry it took so long to handle that... :-/

Regards,
Yann E. MORIN.
