Subject: [PATCH 1/3] sched: fix confusing PFA_NO_NEW_PRIVS constant

From: Tetsuo Handa <penguin-kernel@...ove.SAKURA.ne.jp>

Commit 1d4457f99928 ("sched: move no_new_privs into new atomic flags")
defined PFA_NO_NEW_PRIVS as hexadecimal value, but it is confusing
because it is used as bit number. Redefine it as decimal bit number.
