From 28ea3c7529388c1e4177336a0e655c6c7272fd1c Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Sun, 27 Apr 2014 18:10:43 -0400 Subject: powerpc: Export flush_icache_range Commit aac416fc38c (lkdtm: flush icache and report actions) calls flush_icache_range from a module. It's exported on most architectures that implement it, but not on powerpc. This patch exports it to fix the module link failure.
