You can access gcc side of patch from the following two branches:
svn://gcc.gnu.org/svn/gcc/branches/google/mainorsvn://gcc.gnu.org/svn/gcc/branches/google/gcc-4_6_branch
I have the patch for 2.6.36 kernel and 2.6.34 kernel and I believe I
attached 2.6.36 patch to one of the early review emails. Let me know
you cannot find it.
We do plan to submit to trunk for both gcc and kernel changes. But we
don't expect it happens shortly.
