From b7bab880c795ec620041ef0295cbbbc5a726f414 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 11 Jun 2009 13:05:14 +0100 Subject: FRV: Implement TIF_NOTIFY_RESUME Implement the TIF_NOTIFY_RESUME thread flag, making it call do_notify_resume() which then clears it. This will be made use of later by tracehooks in the new-style ptrace implementation Also discard TIF_IRET as that's not used by FRV.
