From ece51529a470f849ed8652612cc325188c166a9d Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Tue, 6 Aug 2019 12:43:20 -0700 Subject: [PATCH] MIPS: octeon: Remove cpu_has_saa The cpu_has_saa feature macro was added along with Cavium Octeon CPU support back in commit 5b3b16880f40 ("MIPS: Add Cavium OCTEON processor support files to arch/mips/cavium-octeon.") but has never been used. Remove the dead code.
