Should be easy to debug, the compat 2.6.31 code is in
compat/compat-2.6.32.[ch] and since there is no 2.6.33 yet that is
all. That and of course any ifdef which applies on the
compat/patches/.

Well no, I believe what Tim means is the stable compat-wireless
releases which are not based on master git on compat-wireless. These
are based on a branch for the specific stable kernel. The stable
compat-wireless releases use hpa's tree:

git://git.kernel.org/pub/scm/linux/kernel/git/hpa/linux-2.6-allstable.git

and I checkout specific 2.6.3x.y branches. So for 2.6.32 I just use
master though which is based on Linus' tree and the latest *stable*
2.6.32-rcx.
