Davidlohr Bueso b951242a4f blackfin/ptrace: call find_vma with the mmap_sem held 
Performing vma lookups without taking the mm->mmap_sem is asking for
trouble.  While doing the search, the vma in question can be modified or
even removed before returning to the caller.  Take the lock (shared) in
order to avoid races while iterating through the vmacache and/or rbtree.
