This is a note to let you know that I have just added a patch titled ARM: 7772/1: Fix missing flush_kernel_dcache_page() for noMMU to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From d8b09f9a22655b1fe04103d722ec1fdbbbcea75d Mon Sep 17 00:00:00 2001 From: Simon Baatz <gmbnomis@gmail.com> Date: Sat, 22 Jun 2013 22:01:25 +0100 Subject: [PATCH] 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.
