Subject: [PATCH 1/1] kexec-tools: fix build on pre 4.4 kernels
Date: Fri, 5 Feb 2021 09:15:59 +0100 [thread overview]
Message-ID: <20210205081559.15956-1-fede@evolware.org> (raw)
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.
