[PATCH 4.8 05/35] ARC: Dont use "+l" inline asm constraint

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vineet Gupta <vgupta@synopsys.com>

commit 3c7c7a2fc8811bc7097479f69acf2527693d7562 upstream.

Apparenty this is coming in the way of gcc fix which inhibits the usage
of LP_COUNT as a gpr.
