2020-11-19ARM: dts: dra76x: m_can: fix order of clocksMarc Kleine-Budde1-2/+2
According to the bosch,m_can.yaml bindings the first clock shall be the "hclk", while the second clock "cclk". This patch fixes the order accordingly.

2020-11-17Input: atmel_mxt_ts - fix up inverted RESET handlerLinus Walleij10-10/+10
This driver uses GPIO descriptors to drive the touchscreen RESET line. In the existing device trees this has in conflict with intution been flagged as GPIO_ACTIVE_HIGH and the driver then applies the reverse action by driving the line low (setting to 0) to enter reset state and driving the line high (setting to 1) to get out of reset state. The correct way to handle active low GPIO lines is to provide the GPIO_ACTIVE_LOW in the device tree (thus properly describing the hardware) and letting the GPIO framework invert the assertion (driving high) to a low level and vice versa. This is considered a bug since the device trees are incorrectly mis-specifying the line as active high. Fix the driver and all device trees specifying a reset line.

2020-11-17net: wan: Delete the DLCI / SDLA driversXie He1-1/+0
The DLCI driver (dlci.c) implements the Frame Relay protocol. However, we already have another newer and better implementation of Frame Relay provided by the HDLC_FR driver (hdlc_fr.c). The DLCI driver's implementation of Frame Relay is used by only one hardware driver in the kernel - the SDLA driver (sdla.c). The SDLA driver provides Frame Relay support for the Sangoma S50x devices. However, the vendor provides their own driver (along with their own multi-WAN-protocol implementations including Frame Relay), called WANPIPE. I believe most users of the hardware would use the vendor-provided WANPIPE driver instead. (The WANPIPE driver was even once in the kernel, but was deleted in commit 8db60bcf3021 ("[WAN]: Remove broken and unmaintained Sangoma drivers.") because the vendor no longer updated the in-kernel WANPIPE driver.)

The same problem will be hit on all 32-bit architectures that have a physical address space larger than 4GB and happen to not enable sparsemem and include asm/sparsemem.h from asm/pgtable.h. After the initial discussion, I suggested just always defining MAX_POSSIBLE_PHYSMEM_BITS whenever CONFIG_PHYS_ADDR_T_64BIT is set, or provoking a build error otherwise. This addresses all configurations that can currently have this runtime bug, but leaves all other configurations unchanged. I looked up the possible number of bits in source code and datasheets, here is what I found: - on ARC, CONFIG_ARC_HAS_PAE40 controls whether 32 or 40 bits are used - on ARM, CONFIG_LPAE enables 40 bit addressing, without it we never support more than 32 bits, even though supersections in theory allow up to 40 bits as well. - on MIPS, some MIPS32r1 or later chips support 36 bits, and MIPS32r5 XPA supports up to 60 bits in theory, but 40 bits are more than anyone will ever ship - On PowerPC, there are three different implementations of 36 bit addressing, but 32-bit is used without CONFIG_PTE_64BIT - On RISC-V, the normal page table format can support 34 bit addressing. There is no highmem support on RISC-V, so anything above 2GB is unused, but it might be useful to eventually support CONFIG_ZRAM for high pages.

This reverts commit eaf2d2f6895d676dda6c95a652b58594f2887720. The commit eaf2d2f6895d ("ARM: dts: exynos: add input clock to CMU in Exynos4412 Odroid") breaks probing of usb3503 USB hub on Odroid U3. It changes the order of clock drivers probe: the clkout (Exynos PMU) driver is probed before the main clk-exynos4 driver. The clkout driver on Exynos4412 depends on clk-exynos4 but it does not support deferred probe, therefore this dependency and changed probe order causes probe failure. The usb3503 USB hub on Odroid U3 on the other hand requires clkout clock.

2020-11-13crypto: arm/chacha-neon - optimize for non-block size multiplesArd Biesheuvel2-24/+107
The current NEON based ChaCha implementation for ARM is optimized for multiples of 4x the ChaCha block size (64 bytes). This makes sense for block encryption, but given that ChaCha is also often used in the context of networking, it makes sense to consider arbitrary length inputs as well. For example, WireGuard typically uses 1420 byte packets, and performing ChaCha encryption involves 5 invocations of chacha_4block_xor_neon() and 3 invocations of chacha_block_xor_neon(), where the last one also involves a memcpy() using a buffer on the stack to process the final chunk of 1420 % 64 == 12 bytes. Let's optimize for this case as well, by letting chacha_4block_xor_neon() deal with any input size between 64 and 256 bytes, using NEON permutation instructions and overlapping loads and stores. This way, the 140 byte tail of a 1420 byte input buffer can simply be processed in one go. This results in the following performance improvements for 1420 byte blocks, without significant impact on power-of-2 input sizes.

Update the connection in the DT. Since the IRQ line 0 is used for PMIC as well and cannot be shared with the button, make the button polled.

2020-11-04ARM, xtensa: highmem: avoid clobbering non-page aligned memory reservationsArd Biesheuvel1-2/+2
free_highpages() iterates over the free memblock regions in high memory, and marks each page as available for the memory management system. Until commit cddb5ddf2b76 ("arm, xtensa: simplify initialization of high memory pages") it rounded beginning of each region upwards and end of each region downwards. However, after that commit free_highmem() rounds the beginning and end of each region downwards, and we may end up freeing a page that is memblock_reserve()d, resulting in memory corruption. Restore the original rounding of the region boundaries to avoid freeing reserved pages.

2020-11-02ARM: dts: imx6q-prti6q: fix PHY addressOleksij Rempel1-2/+2
Due to bug in the bootloader, the PHY has floating address and may randomly change on each PHY reset. To avoid it, the updated bootloader with the following patch[0] should be used: | ARM: protonic: disable on-die termination to fix PHY bootstrapping | | If on-die termination is enabled, the RXC pin of iMX6 will be pulled | high. Since we already have an 10K pull-down on board, the RXC level on | PHY reset will be ~800mV, which is mostly interpreted as 1. On some | reboots we get 0 instead and kernel can't detect the PHY properly. | | Since the default 0x020e07ac value is 0, it is sufficient to remove this | entry from the affected imxcfg files. | | Since we get stable 0 on pin PHYADDR[2], the PHY address is changed from | 4 to 0. With latest bootloader update, the PHY address will be fixed to "0".

2020-10-27ARM: 9019/1: kprobes: Avoid fortify_panic() when copying optprobe templateAndrew Jeffery2-20/+20
Setting both CONFIG_KPROBES=y and CONFIG_FORTIFY_SOURCE=y on ARM leads to a panic in memcpy() when injecting a kprobe despite the fixes found in commit e46daee53bb5 ("ARM: 8806/1: kprobes: Fix false positive with FORTIFY_SOURCE") and commit 0ac569bf6a79 ("ARM: 8834/1: Fix: kprobes: optimized kprobes illegal instruction"). arch/arm/include/asm/kprobes.h effectively declares the target type of the optprobe_template_entry assembly label as a u32 which leads memcpy()'s __builtin_object_size() call to determine that the pointed-to object is of size four. However, the symbol is used as a handle for the optimised probe assembly template that is at least 96 bytes in size. The symbol's use despite its type blows up the memcpy() in ARM's arch_prepare_optimized_kprobe() with a false-positive fortify_panic() when it should instead copy the optimised probe template into place: ``` $ sudo perf probe -a aspeed_g6_pinctrl_probe [ 158.457252] detected buffer overflow in memcpy [ 158.458069] ------------[ cut here ]------------ [ 158.458283] kernel BUG at lib/string.c:1153!

2020-10-27ARM: OMAP2+: Manage MPU state properly for omap_enter_idle_coupled()Tony Lindgren1-3/+5
Based on more testing, commit 8ca5ee624b4c ("ARM: OMAP2+: Restore MPU power domain if cpu_cluster_pm_enter() fails") is a poor fix for handling cpu_cluster_pm_enter() returned errors. We should not override the cpuidle states with a hardcoded PWRDM_POWER_ON value. Instead, we should use a configured idle state that does not cause the context to be lost. Otherwise we end up configuring a potentially improper state for the MPUSS. We also want to update the returned state index for the selected state. Let's just select the highest power idle state C1 to ensure no context loss is allowed on cpu_cluster_pm_enter() errors. With these changes we can now unconditionally call omap4_enter_lowpower() for WFI like we did earlier before commit 55be2f50336f ("ARM: OMAP2+: Handle errors for cpu_pm"). And we can return the selected state index.
