From 8229f1a044894f84324292608c149f0b4563532b Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 18 Apr 2014 15:07:19 -0700 Subject: mips: export flush_icache_range The lkdtm module performs tests against executable memory ranges, so it needs to flush the icache for proper behaviors. Other architectures already export this, so do the same for MIPS.
