Pull ARM DT and driver fixes from Arnd Bergmann: "For the devicetree files, there are a total of 20 patches, almost entirely for 32-bit machines: - The Allwinner/sun9i r40 SoC dtsi file contains a number of issues, both for correctness and for style that are addressed in separate patches. This causes most of the changed lines of the DT updates this time. - More Allwinner updates fixing the identification of the security system on sun8i/A33, a recent regression of the A83t ethernet, and a few board specific issues on the TBS-A711 macine. - Several bug fixes for OMAP dts files, most notably fixing the timings for the NAND flash on the Nokia N900 that regressed a while ago after the move to configuring them from DT. Some other OMAPs now set the correct dma limits on the L3 bus, and a regression fix addresses lost Ethernet on dm814x - One incorrect setting in the newly added Raspberry Pi Zero W that may cause issues with the SD card controller. - A missing property on the bcm2835 firmware node caused incorrect DMA settings. - An old bug on the oxnas platform causing spurious interrupts is finally addressed. - A regression on the Exynos Midas board broke the OLED panel power supply. - The i.MX6 phycore SoM specified the wrong voltage for the SoC, this is now set to the values from the datasheet. - Some 64-bit machines use a deprecated string to identify the PSCI firmware. There are also several small code fixes addressing mostly serious issues: - Fix the sunxi rsb bus access to no longer return incorrect data when mixing 8 and 16 bit I/O. - Fix a suspend/resume regression on the OMAP2+ lcdc from a missing quirk in the ti-sysc driver - Fix a NULL pointer access from a race in the fsl dpio driver - Fix a v5.5 regression in the exynos-chipid driver that caused an invalid error code probing the device on non-exynos platforms - Fix an out-of-bounds access in the AMD TEE driver" * tag 'arm-soc-fixes-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (24 commits) soc: samsung: chipid: Fix return value on non-Exynos platforms arm64: dts: Fix leftover entry-methods for PSCI ARM: dts: exynos: Fix regulator node aliasing on Midas-based boards ARM: dts: oxnas: Fix clear-mask property ARM: dts: bcm283x: Fix vc4's firmware bus DMA limitations ARM: dts: omap5: Add bus_dma_limit for L3 bus ARM: dts: omap4-droid4: Fix lost touchscreen interrupts ARM: dts: dra7: Add bus_dma_limit for L3 bus ARM: bcm2835-rpi-zero-w: Add missing pinctrl name ARM: dts: sun8i: a33: add the new SS compatible dt-bindings: crypto: add new compatible for A33 SS ARM: dts: sun8i: r40: Move SPI device nodes based on address order ARM: dts: sun8i: r40: Fix register base address for SPI2 and SPI3 ARM: dts: sun8i: r40: Move AHCI device node based on address order ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage soc: fsl: dpio: register dpio irq handlers after dpio create tee: amdtee: out of bounds read in find_session() ARM: dts: N900: fix onenand timings bus: ti-sysc: Fix quirk flags for lcdc on am335x ARM: dts: Fix dm814x Ethernet by changing to use rgmii-id mode ...

crypto: arm64/chacha - correctly walk through blocks

2020-03-20T03:35:27Z

Prior, passing in chunks of 2, 3, or 4, followed by any additional chunks would result in the chacha state counter getting out of sync, resulting in incorrect encryption/decryption, which is a pretty nasty crypto vuln: "why do images look weird on webpages?" WireGuard users never experienced this prior, because we have always, out of tree, used a different crypto library, until the recent Frankenzinc addition. This commit fixes the issue by advancing the pointers and state counter by the actual size processed. It also fixes up a bug in the (optional, costly) stride test that prevented it from running on arm64.

arm64: compat: Fix syscall number of compat_clock_getres

2020-03-19T19:23:46Z

The syscall number of compat_clock_getres was erroneously set to 247 (__NR_io_cancel!) instead of 264. This causes the vDSO fallback of clock_getres() to land on the wrong syscall for compat tasks. Fix the numbering.

arm64: kpti: Fix "kpti=off" when KASLR is enabled

2020-03-19T08:28:43Z

Enabling KASLR forces the use of non-global page-table entries for kernel mappings, as this is a decision that we have to make very early on before mapping the kernel proper. When used in conjunction with the "kpti=off" command-line option, it is possible to use non-global kernel mappings but with the kpti trampoline disabled. Since commit 09e3c22a86f6 ("arm64: Use a variable to store non-global mappings decision"), arm64_kernel_unmapped_at_el0() reflects only the use of non-global mappings and does not take into account whether the kpti trampoline is enabled. This breaks context switching of the TPIDRRO_EL0 register for 64-bit tasks, where the clearing of the register is deferred to the ret-to-user code, but it also breaks the ARM SPE PMU driver which helpfully recommends passing "kpti=off" on the command line! Report whether or not KPTI is actually enabled in arm64_kernel_unmapped_at_el0() and check the 'arm64_use_ng_mappings' global variable directly when determining the protection flags for kernel mappings.
