------------------------------------------------------
Subject: frv: utrace: implement TIF_NOTIFY_RESUME
From: David Howells <dhowells@xxxxxxxxxx>
Implement the TIF_NOTIFY_RESUME thread flag, making it call
do_notify_resume() which then clears it. This will be added to later by
utrace.
Also discard TIF_IRET as that's not used by FRV.
