Alan Cox 56e66ce802 Ordinarily, during a superpage promotion or demotion within a pmap, the ... pmap's lock ensures that other operations on the pmap don't observe the old mapping being broken before the new mapping is established. However, pmap_kextract() doesn't acquire the kernel pmap's lock, so it may observe the broken mapping. And, if it does, it returns an incorrect result. This revision implements a lock-free solution to this problem in pmap_update_entry() and pmap_kextract() because pmap_kextract() can't acquire the kernel pmap's lock.
