[PATCH] freepgt: arch FIRST_USER_ADDRESS 0
Replace misleading definition of FIRST_USER_PGD_NR 0 by definition of FIRST_USER_ADDRESS 0 in all the MMU architectures beyond arm and arm26. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
