Bad page state

[Prasad Koya]

Hi

I still see bad page state and bad spinlock magic after applying
following patches to 2.6.38.8. I see these patches in 3.7.

3ad3d901bbcfb15a5e4690e55350db0899095a68 (31 Jul '12):
mm: mmu_notifier: fix freed page still mapped in secondary MMU


21a92735f660eaecf69a6f2e777f18463760ec32
mm: mmu_notifier: have mmu_notifiers use a global SRCU so they may
safely schedule


70400303ce0c4ced3139499c676d5c79636b0c72
mm: mmu_notifier: make the mmu_notifier srcu static


This is reproducible. Here is the backtrace. Does anyone else see this
issue? I can enable any configs related to debugging if needed.

thank you
