This is a note to let you know that I've just added the patch titled MIPS: Reserve nosave data for hibernation to the 4.5-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: mips-reserve-nosave-data-for-hibernation.patch and it can be found in the queue-4.5 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From a95d069204e178f18476f5499abab0d0d9cbc32c Mon Sep 17 00:00:00 2001 From: Huacai Chen <chenhc@xxxxxxxxxx> Date: Thu, 17 Mar 2016 20:37:10 +0800 Subject: MIPS: Reserve nosave data for hibernation From: Huacai Chen <chenhc@xxxxxxxxxx> commit a95d069204e178f18476f5499abab0d0d9cbc32c upstream. After commit 92923ca3aacef63c92d ("mm: meminit: only set page reserved in the memblock region"), the MIPS hibernation is broken. Because pages in nosave data section should be "reserved", but currently they aren't set to "reserved" at initialization. This patch makes hibernation work again.
