[PATCH AUTOSEL 4.9 17/24] ARC: uacces: remove lp_start, lp_end from clobber list

[Sasha Levin]

From: Vineet Gupta <vgupta@xxxxxxxxxxxx>

[ Upstream commit d5e3c55e01d8b1774b37b4647c30fb22f1d39077 ]

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