[PATCH 0/8] mm: Preemptibility -v9

[Peter Zijlstra]

This series depends on the previous two series:
  - mm: Simplify anon_vma lifetime rules (merged by akpm)
  - mm: mmu_gather rework

These patches make part of the mm a lot more preemptible. It converts
i_mmap_lock and anon_vma->lock to mutexes which together with the mmu_gather
rework makes mmu_gather preemptible as well.

Making i_mmap_lock a mutex also enables a clean-up of the truncate code.

This also allows for preemptible mmu_notifiers, something that XPMEM I think
wants.

Furthermore, it removes the new and universially detested unmap_mutex.
