Okay, I recommend that you (and everyone else) uses the tree at:

git://git.armlinux.org.uk/~rmk/kexec-tools.git

which is now up to date with mainline, plus includes the necessary
fixes for the mis-merge, and subsequent fixes from a previous size-
related problem from January.

There's also a ti-keystone2 branch which contains an additional
(hacky and untested) patch which allows reading the coredump
generated by kexec on a crash.
