CentOS will not make changes to the distro kernel because it aims to
be 100% binary compatible (including bugs). However, it you submit
the patch you have, it might be included in the centosplus kernel. I
suggest you open a report at http://bugs.centos.org with a detailed
description of the problem and upload your patch.
Another thing you want to try is to open a bugzilla upstream. If the
patch is incorporated in the upstream kernel, it will then be in the
CentOS kernel.
The kABI fix you mentioned is not a problem. It is just a note. You
can still build custom kernels by following the instructions on the
Wiki.
