Thanks for reporting the problem and finding the commit that caused it.
The only thing in commit 5c01cdd2d4bc which can affect kexec_load is the
fact that struct kexec_segment has a new member.
This is probably breaking the ABI on ARM, then. I verified that kexec_load
kept working on ppc64le with a kexec binary compiled with the original
struct kexec_segment definition, but apparently I got lucky.
I'll prepare a new version of the kexec buffer hand-over series which
doesn't touch struct kexec_segment.
