generalize lgread_u32/lgwrite_u32.
Jes complains that page table code still uses lgread_u32 even though it now uses general kernel pte types. The best thing to do is to generalize lgread_u32 and lgwrite_u32. This means we lose the efficiency of getuser(). We could potentially regain it if we used __copy_from_user instead of copy_from_user, but I'm not certain that our range check is equivalent to access_ok() on all platforms.
