Hi Andrew,
This is because in mm.git you have patches that move kexec_handover*
to kernel/liveupdate/ (and they fix this build problem), but
linux-next does not have these patches. The patch I sent is a fixup
for "kho: warn and fail on metadata or preserved memory in scratch
area" patch.

Oh, OK. Please tell others these things :(
I think I have it all sorted out, thanks.
