2018-08-30ARM: dts: socfpga: update NAND clocking for c5/a5Dinh Nguyen
The NAND IP needs 3 clocks(nand_x_clk, nand_clk, and nand_ecc_clk). The nand_x_clk and nand_ecc_clk are derived from the nand_clk. The nand_x_clk has a fixed divider of 4. Also, update the NAND dts property with the correct clocks property. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org> --- v2: add nand_ecc_clk and update commit message

The NAND IP needs 3 clocks(nand_x_clk, nand_clk, and nand_ecc_clk). This patch adds a nand_clk, which is derived from the nand_x_clk, but has a fixed divider of 4, and the nand_ecc_clk, which is derived from the nand_x_clk. Update the NAND node to use the additional clocks. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org> --- v2: add nand_ecc_clk and update commit message

2018-08-30arm/arm64: smccc-1.1: Handle function result as parametersMarc Zyngier
If someone has the silly idea to write something along those lines: extern u64 foo(void); void bar(struct arm_smccc_res *res) { arm_smccc_1_1_smc(0xbad, foo(), res); } they are in for a surprise, as this gets compiled as: 0000000000000588 <bar>: 588: a9be7bfd stp x29, x30, [sp, #-32]! 58c: 910003fd mov x29, sp 590: f9000bf3 str x19, [sp, #16] 594: aa0003f3 mov x19, x0 598: aa1e03e0 mov x0, x30 59c: 94000000 bl 0 <_mcount> 5a0: 94000000 bl 0 <foo> 5a4: aa0003e1 mov x1, x0 5a8: d4000003 smc #0x0 5ac: b4000073 cbz x19, 5b8 <bar+0x30> 5b0: a9000660 stp x0, x1, [x19] 5b4: a9010e62 stp x2, x3, [x19, #16] 5b8: f9400bf3 ldr x19, [sp, #16] 5bc: a8c27bfd ldp x29, x30, [sp], #32 5c0: d65f03c0 ret 5c4: d503201f nop The call to foo "overwrites" the x0 register for the return value, and we end up calling the wrong secure service.

2018-08-30watchdog: Mark watchdog touch functions as notraceVincent Whitchurch
Some architectures need to use stop_machine() to patch functions for ftrace, and the assumption is that the stopped CPUs do not make function calls to traceable functions when they are in the stopped state. Commit ce4f06dcbb5d ("stop_machine: Touch_nmi_watchdog() after MULTI_STOP_PREPARE") added calls to the watchdog touch functions from the stopped CPUs and those functions lack notrace annotations. This leads to crashes when enabling/disabling ftrace on ARM kernels built with the Thumb-2 instruction set. Fix it by adding the necessary notrace annotations.

2018-08-30x86/entry/64: Wipe KASAN stack shadow before rewind_stack_do_exit()Jann Horn
Reset the KASAN shadow state of the task stack before rewinding RSP. Without this, a kernel oops will leave parts of the stack poisoned, and code running under do_exit() can trip over such poisoned regions and cause nonsensical false-positive KASAN reports about stack-out-of-bounds bugs. This does not wipe the exception stacks; if an oops happens on an exception stack, it might result in random KASAN false-positives from other tasks afterwards. This is probably relatively uninteresting, since if the kernel oopses on an exception stack, there are most likely bigger things to worry about. It'd be more interesting if vmapped stacks and KASAN were compatible, since then handle_stack_overflow() would oops from exception stack context.

2018-08-29powerpc: disable support for relative ksymtab referencesArd Biesheuvel
The newly added code that emits ksymtab entries as pairs of 32-bit relative references interacts poorly with the way powerpc lays out its address space: when a module exports a per-CPU variable, the primary module region covering the ksymtab entry -and thus the 32-bit relative reference- is too far away from the actual per-CPU variable's base address (to which the per-CPU offsets are applied to obtain the respective address of each CPU's copy), resulting in corruption when the module loader attempts to resolve symbol references of modules that are loaded on top and link to the exported per-CPU symbol. So let's disable this feature on powerpc. Even though it implements CONFIG_RELOCATABLE, it does not implement CONFIG_RANDOMIZE_BASE and so KASLR kernels (which are the main target of the feature) do not exist on powerpc anyway.

100 ms is not enough time for the LSPCON adapter on Intel NUC devices to settle. This causes dropped display modes at boot or screen reconfiguration.

git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes i.MX fixes for 4.19: - i.MX display folks decided to switch MXS display driver from legacy FB to DRM during 4.19 merge window. It leads to a fallout on some Freescale/NXP development boards with Seiko 43WVF1G panel, because this DRM panel driver is not enabled in i.MX defconfig. Here is a series from Fabio to convert i.MX23/28 EVK DT to Seiko 43WVF1G panel bindings and enable the panel driver in i.MX defconfig, so that users can still get functional LCD on these boards by default. - A fix from Leonard to revert incorrect legacy PCI irq mapping in i.MX7 device tree, that was caused by document errors. * tag 'imx-fixes-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: ARM: imx_v6_v7_defconfig: Select CONFIG_DRM_PANEL_SEIKO_43WVF1G ARM: mxs_defconfig: Select CONFIG_DRM_PANEL_SEIKO_43WVF1G ARM: dts: imx23-evk: Convert to the new display bindings ARM: dts: imx23-evk: Move regulators outside simple-bus ARM: dts: imx28-evk: Convert to the new display bindings ARM: dts: imx28-evk: Move regulators outside simple-bus Revert "ARM: dts: imx7d: Invert legacy PCI irq mapping" Signed-off-by: Olof Johansson <olof@lixom.net>

2018-08-29of: add helper to lookup compatible child nodeJohan Hovold
Add of_get_compatible_child() helper that can be used to lookup compatible child nodes. Several drivers currently use of_find_compatible_node() to lookup child nodes while failing to notice that the of_find_ functions search the entire tree depth-first (from a given start node) and therefore can match unrelated nodes. The fact that these functions also drop a reference to the node they start searching from (e.g. the parent node) is typically also overlooked, something which can lead to use-after-free bugs.
