This is commit 1de14c3c5cbc9bb17e9dcc648cda51c0c85d54b9. The full
commit message says about the bug: "Ingo guesses this got introduced by
commit 611ae8e3f520 ("x86/tlb: enable tlb flush range support for x86")
since that code started to free unused pagetables." And that was in
Linux 3.6. So, what makes you think that you're seeing the same bug in
Linux 3.2?
