This is a note to let you know that I've just added the patch titled ARM: OMAP2+: Fix ppa_zero_params and ppa_por_params for rodata to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm-omap2-fix-ppa_zero_params-and-ppa_por_params-for-rodata.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 4da597d16602d14405b71a18d45e1c59f28f0fd2 Mon Sep 17 00:00:00 2001 From: Tony Lindgren <tony@xxxxxxxxxxx> Date: Thu, 14 Jan 2016 12:20:48 -0800 Subject: ARM: OMAP2+: Fix ppa_zero_params and ppa_por_params for rodata From: Tony Lindgren <tony@xxxxxxxxxxx> commit 4da597d16602d14405b71a18d45e1c59f28f0fd2 upstream. We don't want to write to .text so let's move ppa_zero_params and ppa_por_params to .data and access them via pointers. Note that I have not been able to test as we I don't have a HS omap4 to test with. The code has been changed in similar way as for omap3 though.
