I'll not comment on the big ARM patch, but in reinstating it, you need to
make sure it gets back into EXTRA_DIST. This wasn't removed by Xerxes so
it won't be reinstated in a inversion of that patch:
2011-10-05 Andrew John Hughes <ahughes at redhat.com>
(EXTRA_DIST): Complete ARM port
removal by removing arm_port.
Without that, the ARM port won't ship in our tarballs. You'll also want
to remove/replace the NEWS item that says the ARM port has been removed in
