2018-03-21ARM: OMAP: Fix SRAM W+X mappingTony Lindgren
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.

2018-03-14ARM: dts: aspeed: Add default memory nodeJoel Stanley
When we removed the inclusion of skeleton.dtsi from the device trees, we broke booting for systems with bootloaders that aren't device tre aware. This can be seen, for example, when appending the device tree blob to the kernel image. The reason booting broke was that the kernel lacked the device_type label in the memory node. Add in a default memory node wth the device_type. It can contain the memory address as the location is fixed for each SoC generation, but the size needs to be added by the bootloader or the board specific dts.

2018-03-07ARM: ux500: Fix PMU IRQ regressionLinus Walleij
Commit 2b05f6ae1ee5 ("ARM: ux500: remove PMU IRQ bouncer") deleted some code to bounce and work around the weird PMU IRQs in the DB8500 ASIC, but did a semantic mistake: since the auxdata was now unused, the call to of_platform_populate() was removed, but this does not work: the default platform population will only kick in if .init_machine() is assigned NULL, and since the U8540 was still using the callback that was not the case. Fix this by reinstating the call to of_platform_populate(), but pass NULL as auxdata.

The top-level page of the schematics says the board has 2GB, but when you end-up scrolling to page 6, you see two chips of 4GBit (512MB) but what the bootloader really initializes only 512MB, any attempt to use more than that results in data aborts.

2018-02-26ARM: orion5x: Revert commit 4904dbda41c8.David S. Miller
It is not valid for orion5x to use mac_pton(). First of all, the orion5x buffer is not NULL terminated. mac_pton() has no business operating on non-NULL terminated buffers because only the caller can know that this is valid and in what manner it is ok to parse this NULL'less buffer. Second of all, orion5x operates on an __iomem pointer, which cannot be dereferenced using normal C pointer operations. Accesses to such areas much be performed with the proper iomem accessors.

To fix that, I get rid of the extra symbol and rewrite the initialization in a simpler way that assigns both the bus_id and modalias statically. I spotted another theoretical bug in the same place, where d->netdev[i] may be an out of bounds access, this can be fixed by moving the device assignment into the loop.

2018-02-22arm: zx: dts: Remove leading 0x and 0s from bindings notationMathieu Malaterre
Improve the DTS files by removing all the leading "0x" and zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading "0x" and Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C For simplicity, two sed expressions were used to solve each warnings separately. To make the regex expression more robust a few other issues were resolved, namely setting unit-address to lower case, and adding a whitespace before the the opening curly brace: https://elinux.org/Device_Tree_Linux#Linux_conventions This will solve as a side effect warning: Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>" This is a follow up to commit 4c9847b7375a ("dt-bindings: Remove leading 0x from bindings notation") Reported-by: David Daney <ddaney@caviumnetworks.com> Suggested-by: Rob Herring <robh@kernel.org> Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2018-02-16ARM: dts: rockchip: Fix DWMMC clocksRobin Murphy
Trying to boot an RK3328 box with an HS200-capable eMMC, I see said eMMC fail to initialise as it can't run its tuning procedure, because the sample clock is missing. Upon closer inspection, whilst the clock is present in the DT, its name is subtly incorrect per the binding, so __of_clk_get_by_name() never finds it. By inspection, the drive clock suffers from a similar problem, so has never worked properly either. This error has propagated across the 32-bit DTs too, so fix those up.

2018-02-15ARM: kvm: fix building with gcc-8Arnd Bergmann
In banked-sr.c, we use a top-level '__asm__(".arch_extension virt")' statement to allow compilation of a multi-CPU kernel for ARMv6 and older ARMv7-A that don't normally support access to the banked registers. This is considered to be a programming error by the gcc developers and will no longer work in gcc-8, where we now get a build error: /tmp/cc4Qy7GR.s:34: Error: Banked registers are not available with this architecture. -- `mrs r3,SP_usr' /tmp/cc4Qy7GR.s:41: Error: Banked registers are not available with this architecture. -- `mrs r3,ELR_hyp' /tmp/cc4Qy7GR.s:55: Error: Banked registers are not available with this architecture. -- `mrs r3,SP_svc' /tmp/cc4Qy7GR.s:62: Error: Banked registers are not available with this architecture. -- `mrs r3,LR_svc' /tmp/cc4Qy7GR.s:69: Error: Banked registers are not available with this architecture. -- `mrs r3,SPSR_svc' /tmp/cc4Qy7GR.s:76: Error: Banked registers are not available with this architecture. -- `mrs r3,SP_abt' Passign the '-march-armv7ve' flag to gcc works, and is ok here, because we know the functions won't ever be called on pre-ARMv7VE machines. Unfortunately, older compiler versions (4.8 and earlier) do not understand that flag, so we still need to keep the asm around. Backporting to stable kernels (4.6+) is needed to allow those to be built with future compilers as well.

Remove all casts from data pointers passed to debugfs_create_*() functions, as such casts prevent the compiler from flagging bugs.

2018-02-14ARM: OMAP3: Fix prm wake interrupt for resumeTony Lindgren
For platform_suspend_ops, the finish call is too late to re-enable wake irqs and we need re-enable wake irqs on wake call instead. Otherwise noirq resume for devices has already happened. And then dev_pm_disarm_wake_irq() has already disabled the dedicated wake irqs when the interrupt triggers and the wake irq is never handled. For devices that are already in PM runtime suspended state when we enter suspend this means that a possible wake irq will never trigger. And this can lead into a situation where a device has a pending padconf wake irq, and the device will stay unresponsive to any further wake irqs. This issue can be easily reproduced by setting serial console log level to zero, letting the serial console idle, and suspend the system from an ssh terminal. Then try to wake up the system by typing to the serial console. Note that this affects only omap3 PRM interrupt as that's currently the only omap variant that does anything in omap_pm_wake(). In general, for the wake irqs to work, the interrupt must have either IRQF_NO_SUSPEND or IRQF_EARLY_RESUME set for it to trigger before dev_pm_disarm_wake_irq() disables the wake irqs.

2018-02-14ARM: OMAP2+: timer: fix a kmemleak caused in omap_get_timer_dtQi Hou
When more than one GP timers are used as kernel system timers and the corresponding nodes in device-tree are marked with the same "disabled" property, then the "attr" field of the property will be initialized more than once as the property being added to sys file system via __of_add_property_sysfs(). In __of_add_property_sysfs(), the "name" field of pp->attr.attr is set directly to the return value of safe_name(), without taking care of whether it's already a valid pointer to a memory block. If it is, its old value will always be overwritten by the new one and the memory block allocated before will a "ghost", then a kmemleak happened. That the same "disabled" property being added to different nodes of device tree would cause that kind of kmemleak overhead, at least once. To fix it, allocate the property dynamically, and delete static one. Signed-off-by: Qi Hou <qi.hou@windriver.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
