Subject: [PATCH AUTOSEL 4.4 11/15] ARC: uacces: remove lp_start, lp_end from clobber list
Date: Wed, 13 Mar 2019 15:17:57 -0400	[thread overview]
Message-ID: <20190313191806.160547-11-sashal@kernel.org> (raw)
In-Reply-To: <20190313191806.160547-1-sashal@kernel.org>

From: Vineet Gupta <vgupta@synopsys.com>

[ Upstream commit d5e3c55e01d8b1774b37b4647c30fb22f1d39077 ]

Newer ARC gcc handles lp_start, lp_end in a different way and doesn't
like them in the clobber list.
