Subject: [PATCH AUTOSEL 5.5 63/66] csky: Fixup ftrace modify panic
Date: Mon, 2 Mar 2020 21:46:12 -0500 [thread overview]
Message-ID: <20200303024615.8889-63-sashal@kernel.org> (raw)
In-Reply-To: <20200303024615.8889-1-sashal@kernel.org>
From: Guo Ren <guoren@linux.alibaba.com>
[ Upstream commit 359ae00d12589c31cf103894d0f32588d523ca83 ]
During ftrace init, linux will replace all function prologues
(call_mcout) with nops, but it need flush_dcache and
invalidate_icache to make it work. So flush_cache functions
couldn't be nested called by ftrace framework.
