Subject: [PATCH 1/3] powerpc: Reclaim two unused thread_info flag bits
Date: Mon, 13 Jan 2014 15:56:28 +1100 [thread overview]
Message-ID: <1389588990-25953-2-git-send-email-paulus@samba.org> (raw)
In-Reply-To: <1389588990-25953-1-git-send-email-paulus@samba.org>
TIF_PERFMON_WORK and TIF_PERFMON_CTXSW are completely unused. They
appear to be related to the old perfmon2 code, which has been
superseded by the perf_event infrastructure. This removes their
definitions so that the bits can be used for other purposes.
