From bdd1c06a9df5155e6338f01100ad5c4a6c6dbffc Mon Sep 17 00:00:00 2001 From: Simon Baatz Date: Sat, 22 Jun 2013 22:01:25 +0100 Subject: ARM: 7772/1: Fix missing flush_kernel_dcache_page() for noMMU commit 63384fd0b1509acf522a8a8fcede09087eedb7df upstream. Commit 1bc3974 (ARM: 7755/1: handle user space mapped pages in flush_kernel_dcache_page) moved the implementation of flush_kernel_dcache_page() into mm/flush.c but did not implement it on noMMU ARM.
