    Subject[PATCH AUTOSEL 4.19 34/48] ARC: uacces: remove lp_start, lp_end from clobber list
    Date
    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.
