of pmap_load_clear(), in places where we don't care about the page table entry's prior contents. Eliminate an unnecessary pmap_load() from pmap_remove_all(). Instead, use the value returned by the pmap_load_clear() on the very next line. (In the future, when we support "hardware dirty bit management", using the value from the pmap_load() rather than the pmap_load_clear() would have actually been an error because the dirty bit could potentially change between the pmap_load() and the pmap_load_clear().) A KASSERT() in pmap_enter(), which originated in the amd64 pmap, was meant to check the value returned by the pmap_load_clear() on the previous line. However, we were ignoring the value returned by the pmap_load_clear(), and so the KASSERT() was not serving its intended purpose. Use the value returned by the pmap_load_clear() in the KASSERT().
