[PATCH] compat_sys_futex() warning fix

kernel/futex_compat.c: In function `compat_sys_futex':
kernel/futex_compat.c:140: warning: passing arg 1 of `do_futex' makes integer from pointer without a cast
kernel/futex_compat.c:140: warning: passing arg 5 of `do_futex' makes integer from pointer without a cast

Not sure what Ingo was thinking of here.  Put the casts back in.
