Carlos Llamas 072010abc3 binder: replace alloc->vma with alloc->mapped ... It is unsafe to use alloc->vma outside of the mmap_sem. Instead, add a new boolean alloc->mapped to save the vma state (mapped or unmmaped) and use this as a replacement for alloc->vma to validate several paths. Using the alloc->vma caused several performance and security issues in the past. Now that it has been replaced with either vm_lookup() or the alloc->mapped state, we can finally remove it.
