There is logical conflict between

commit 37002bc6b603 ("docs: move s390 under arch")

from the s390 tree:
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux tags/s390-6.6-1
and

commit 89cde455915f ("kexec: consolidate kexec and crash options into kernel/Kconfig.kexec")

from Andrew's tree:
git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm mm-nonmm-stable

The commit in Andrew's tree introduces kernel/Kconfic.kexec and uses the
old location for Documentation (which is correct for Andrew's tree). So
when merging the s390 tree and Andrew's tree into Linus' tree that should
be fixed as well (btw.: this is not "fixed" in linux-next).

So I guess the size of the merge commit diff is simply a result of
kernel/Kconfig.exec not being present in both trees and being modified with
the merge, and therefore the complete file is part of the diff.
