From 6e90049162b92e683641966e4cdc67febe3c8fc5 Mon Sep 17 00:00:00 2001 From: Jiaxun Yang Date: Tue, 4 Apr 2023 10:33:45 +0100 Subject: [PATCH] MIPS: c-octeon: Provide alternative SMP cache flush function Currently c-octeon relies on octeon's own smp function to flush I-Cache. However this function is not available on generic platform. Just use smp_call_function_many on generic platform.
