sched: fix confusing PFA_NO_NEW_PRIVS constant
PATCH RESEND v2 1/3 sched: fix confusing PFA_NO_NEW_PRIVS constant
From: Tetsuo Handa <penguin-kernel-JPay3/[email protected]>
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.
Note this changes the bit position of PFA_NOW_NEW_PRIVS from 1 to 0.
