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-3.8.y-queue branch of the 3.8.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-3.8.y-queue This patch is scheduled to be released in version 3.8.13.4. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 9785c65253a2467c479f5c5565462904a4e0d03c Mon Sep 17 00:00:00 2001 From: Simon Baatz <gmbnomis@gmail.com> 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.
