From ededb49a9aa54960fce35c705d505d409f5b5483 Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Mon, 23 May 2016 16:22:23 -0700 Subject: [PATCH] m32r: fix build failure m32r allmodconfig build was failing with the error: ERROR: "smp_flush_cache_all" [drivers/misc/lkdtm.ko] undefined! lkdtm driver at drivers/misc is using flush_icache_range() which for m32r is defined as smp_flush_cache_all() if CONFIG_SMP is defined. But as smp_flush_cache_all() was not exported so the build was failing with the error of undefined symbol.
