2022-09-28arm64: dts: uniphier: Add USB-device support for PXs3 reference boardKunihiko Hayashi
PXs3 reference board can change each USB port 0 and 1 to device mode with jumpers. Prepare devicetree sources for USB port 0 and 1. This specifies dr_mode, pinctrl, and some quirks and removes nodes for unused phys and vbus-supply properties.

2022-09-28ARM: Drop CMDLINE_* dependency on ATAGSGeert Uytterhoeven
On arm32, the configuration options to specify the kernel command line type depend on ATAGS. However, the actual CMDLINE cofiguration option does not depend on ATAGS, and the code that handles this is not specific to ATAGS (see drivers/of/fdt.c:early_init_dt_scan_chosen()). Hence users who desire to override the kernel command line on arm32 must enable support for ATAGS, even on a pure-DT system. Other architectures (arm64, loongarch, microblaze, nios2, powerpc, and riscv) do not impose such a restriction. Hence drop the dependency on ATAGS.

2022-09-28ARM: Drop CMDLINE_FORCE dependency on !ARCH_MULTIPLATFORMGeert Uytterhoeven
On older platforms that boot an image with an appended DTB, or where the boot loader has no support for updating chosen/bootargs, it is common to rely on CMDLINE_FORCE. While a fixed command line can make the kernel unbootable on other platforms, it is not guaranteed to cause that. E.g. all Renesas boards use the same chosen/bootargs in upstream DTS, which works fine if your DHCP server hands out proper nfsroot parameters.

This is useful on !virt platforms for kexec, so change things from BI_VIRT_RNG_SEED to be BI_RNG_SEED, and simply remove BI_VIRT_RNG_SEED because it only ever lasted one release, and nothing is broken by not having it. At the same time, keep a comment noting that it's been removed, so that ID isn't reused. In addition, we previously documented 2-byte alignment, but 4-byte alignment is actually necessary, so update that comment.

2022-09-28m68k: Process bootinfo records before saving themJason A. Donenfeld
The RNG seed boot record is memzeroed after processing, in order to preserve forward secrecy. By saving the bootinfo for procfs prior to that, forward secrecy is violated, since it becomes possible to recover past states. So, save the bootinfo block only after first processing them.

2022-09-28i2c: microchip: pci1xxxx: Add driver for I2C host controller in ↵Tharun Kumar P
multifunction endpoint of pci1xxxx switch Microchip pci1xxxx is an unmanaged PCIe3.1a Switch for Consumer, Industrial and Automotive applications. This switch has multiple downstream ports. In one of the Switch's Downstream port, there is a multifunction endpoint for peripherals which includes an I2C host controller. The I2C function in the endpoint operates at 100KHz, 400KHz and 1 MHz and has buffer depth of 128 bytes. This patch provides the I2C controller driver for the I2C function of the switch.

2022-09-29kbuild: list sub-directories in ./KbuildMasahiro Yamada
Use the ordinary obj-y syntax to list subdirectories. Note1: Previously, the link order of lib-y depended on CONFIG_MODULES; lib-y was linked before drivers-y when CONFIG_MODULES=y, otherwise after drivers-y. This was a bug of commit 7273ad2b08f8 ("kbuild: link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y"), but it was not a big deal after all. Now, all objects listed in lib-y are linked last, irrespective of CONFIG_MODULES. Note2: Finally, the single target build in arch/*/lib/ works correctly. There was a bug report about this.

2022-09-29linux/export: use inline assembler to populate symbol CRCsMasahiro Yamada
Since commit 7b4537199a4a ("kbuild: link symbol CRCs at final link, removing CONFIG_MODULE_REL_CRCS"), the module versioning on the (non-upstreamed-yet) kvx Linux port is broken due to unexpected padding for __crc_* symbols. The kvx GCC adds padding so u32 gets 8-byte alignment instead of 4. I do not know if this happens for upstream architectures in general, but any compiler has the freedom to insert padding for faster access. Use the inline assembler to directly specify the wanted data layout. This is how we previously did before the breakage.
