A split function was added to vm_operations_struct to determine if a mapping can be split. This was mostly for device-dax and hugetlbfs mappings which have specific alignment constraints. Mappings initiated via shmget/shmat have their original vm_ops overwritten with shm_vm_ops. shm_vm_ops functions will call back to the original vm_ops if needed.

We are still using custom SRAM code for some SoCs and are not marking the PM code mapped to SRAM as read-only and executable after we're done. With CONFIG_DEBUG_WX=y, we will get "Found insecure W+X mapping at address" warning. Let's fix this issue the same way as commit 728bbe75c82f ("misc: sram: Introduce support code for protect-exec sram type") is doing for drivers/misc/sram-exec.c. On omap3, we need to restore SRAM when returning from off mode after idle, so init time configuration is not enough. And as we no longer have users for omap_sram_push_address() we can make it static while at it. Note that eventually we should be using sram-exec.c for all SoCs.

Patch "ARM: dts: sun6i: a31s: bpi-m2: add missing regulators" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: dts: sun6i: a31s: bpi-m2: add missing regulators to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm-dts-sun6i-a31s-bpi-m2-add-missing-regulators.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 70b8d21496758dd7ff600ec9de0ee3812fac7a40 Mon Sep 17 00:00:00 2001 From: Philipp Rossak <embed3d(a)gmail.com> Date: Wed, 14 Feb 2018 15:10:25 +0100 Subject: ARM: dts: sun6i: a31s: bpi-m2: add missing regulators From: Philipp Rossak <embed3d(a)gmail.com> commit 70b8d21496758dd7ff600ec9de0ee3812fac7a40 upstream. This patch fixes a bootproblem with the Bananapi M2 board. Since there are some regulators missing we add them right now. Those values come from the schematic, below you can find a small overview: * reg_aldo1: 3,3V, powers the wifi * reg_aldo2: 2,5V, powers the IO of the RTL8211E * reg_aldo3: 3,3V, powers the audio * reg_dldo1: 3,0V, powers the RTL8211E * reg_dldo2: 2,8V, powers the analog part of the csi * reg_dldo3: 3,3V, powers misc * reg_eldo1: 1,8V, powers the csi * reg_ldo_io1:1,8V, powers the gpio * reg_dc5ldo: needs to be always on This patch updates also the vmmc-supply properties on the mmc0 and mmc2 node to use the allready existent regulators. We can now remove the sunxi-common-regulators.dtsi include since we don't need it anymore.
