Location of nx-emu patches
I noticed that Ubuntu modifies it's i386 kernels so that CPU's that don't support PAE+NX are capable of 'emulating' this. Now these patches are called the 'nx-emu' patches. I saw this in the patchlog of the stock Ubuntu kernel.
However, the kernel of this computer (from my parents) is pinned down to kernel 3.4 because nouveau fully works on this specific version. So I now use git for the 'kernel version management' but I'm unable to find the source for these patches.
I was wondering, do you guys now where I can find the upstream git repo, sourceforge, git.kernel.org site from the author that creates these nx-emu patches? I saw that Ingo Molnar was mentioned, but googling didn't help much.
