Yes, the only problem was that due to acinclude.m4 between the modified files.
So I also needed to run
autoreconf -f -i
but it fails on CentOS 6.3

configure.ac:15: error: Autoconf version 2.64 or higher is required
configure.ac:15: the top level
autom4te: /usr/bin/m4 failed with exit status: 63
aclocal: autom4te failed with exit status: 63
autoreconf: aclocal failed with exit status: 63

release packages are
autoconf-2.63-5.1.el6.noarch
automake-1.11.1-1.2.el6.noarch

I solved running the autoreconf command on a Fedora 17 system against
the patched tree and then recomposing the tar.gz and then build
successfully on CentOS 6.3 via the provided spec file.

Also, during build I got

Processing files: kmod-openvswitch-1.6.1-1.el6.x86_64
Finding  Provides: /usr/lib/rpm/redhat/find-provides

The kernel ABI reference files (provided by kabi-whitelists) were not found.
No compatibility check was performed. Please install the kABI reference files
and rebuild if you would like to verify compatibility with kernel ABI.

It could be useful to include kabi-whitelists between the
BuildRequires directives for openswitch-kmod


btw: I also had to apply for 6.3 a workaround as in
https://bugzilla.redhat.com/show_bug.cgi?id=842038
to get at the end:

The following kernel symbols are not guaranteed to remain compatible with
future kernel updates to this RHEL release:

        genl_register_family_with_ops

        nlmsg_notify

Red Hat recommends that you consider using only official kernel ABI symbols
where possible. Requests for additions to the kernel ABI can be filed with
your partner or customer representative (component: driver-update-program).
