FWIW, I just had a look at git://sopc.et.ntust.edu.tw/git/linux-2.6. Is that the one you are working on?
The code there is still based on 2.6.30, which does not yet have all the new header file. When you (or someone else) do the port to 2.6.31, please go through each header file and see if you can change it to use the asm-generic version.
For most of the exported files, that will mean a user space ABI change, so you need to rebuild your libc, but it will significantly reduce the amount of (duplicate) code in the architecture tree.
