[PATCH] mm: fixup do_wp_page()
Wrt. the recent modifications in do_wp_page() Hugh Dickins pointed out: "I now realize it's right to the first order (normal case) and to the second order (ptrace poke), but not to the third order (ptrace poke anon page here to be COWed - perhaps can't occur without intervening mprotects)." This patch restores the old COW behaviour for anonymous pages.
