From 92c568c82ee74cb8343620d14190d9c1169e9f71 Mon Sep 17 00:00:00 2001 From: Jiaxun Yang Date: Tue, 4 Apr 2023 10:33:44 +0100 Subject: [PATCH] MIPS: cpu-features: Enable octeon_cache by cpu_type [ Upstream commit f641519409a73403ee6612b8648b95a688ab85c2 ] cpu_has_octeon_cache was tied to 0 for generic cpu-features, whith this generic kernel built for octeon CPU won't boot. Just enable this flag by cpu_type. It won't hurt orther platforms because compiler will eliminate the code path on other processors.
