Subject: [PATCH 3/7] clocksource: pistachio: fix ftrace
Date: Tue, 20 Oct 2015 16:02:36 +0800	[thread overview]
Message-ID: <1445328160-402-4-git-send-email-jszhang@marvell.com> (raw)
In-Reply-To: <1445328160-402-1-git-send-email-jszhang@marvell.com>

Currently pistachio can be used as a scheduler clock, we properly marked
pistachio_read_sched_clock() as notrace. But we then call another function
pistachio_clocksource_read_cycles() that _wasn't_ notrace.

This patch fix this by adding notrace attribute to the
pistachio_clocksource_read_cycles() function.
