Pull ARM devicetree updates from Arnd Bergmann: "Most of the changes fall into one of three categories: adding support for additional devices on existing machines, cleaning up issues found by the ongoing conversion to machine-readable bindings, and addressing minor mistakes in the existing DT data. Across SoC vendors, Qualcomm and Freescale stick out as getting the most updates, which corresponds to their dominance in the mobile phone and embedded industrial markets, respectively. There are 636 non-merge changeset in this branch, which is a little lower than most times, but more importantly we only add 36 machine files, which is about half of what we had the past few releases. Eight new SoCs are added, but all of them are variations of already supported SoC families, and most of them come with one reference board design from the SoC vendor: - Mediatek MT8186 is a Chromebook/Tablet type SoC, similar to the MT65xx series of phone SoCs, with two Cortex-A76 and six Cortex-A55 cores. - TI AM62A is another member of the K3 family with Cortex-A53 cores, this one is targetted at Video/Vision processing for industrial and automotive applications. - NXP i.MX8DXL is another chip for this market in the ever-growing i.MX8 family, this one again with two Cortex-A35 cores. - Renesas R-Car H3Ne-1.7G (R8A779MB) and R-Car V3H2 (R8A77980A) are minor updates of R8A77951 and R8A77980, respectively. - Qualcomm IPQ8064-v2.0, IPQ8062 and IPQ8065 are all variants of the IPQ8064 chip, with minimally different features. The AMD Pensando Elba and Apple M1 Ultra SoC support was getting close this time, but in the end did not make the cut. The new machines based on existing SoC support are fairly uneventful: - Sony Xperia 1 IV is a fairly recent phone based on Qualcomm Snapdragon 8 Gen 1. - Three Samsung phones based on Snapdragon 410: Galaxy E5, E7 and Grand Max. These are added for both 32-bit and 64-bit kernels, as they originally shipped running 32-bit code. - Two new servers using AST2600 BMCs: AMD DaytonaX and Ampere Mt. Mitchell - Three new machines based on Rockchips RK3399 and RK3566: Anberic RG353P and RG503, Pine64 Pinephone Pro, Open AI Lab - Multiple NXP i.MX6/i.MX8 based boards: Kontron SL/BL i.MX8MM OSM-S, i.MX8MM Gateworks GW7904, MSC SM2S-IMX8PLUS SoM and carrier board - Two development boards in the Microchip AT91 family: SAMA5D3-EDS and lan966x-pcb8290. - Minor variants of existing boards using Amlogic, Broadcom, Marvell, Rockchips, Freescale Layerscape and Socionext Uniphier SoCs" * tag 'arm-dt-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (617 commits) Revert "ARM: dts: BCM5301X: Add basic PCI controller properties" ARM: dts: s5pv210: correct double "pins" in pinmux node ARM: dts: exynos: fix polarity of VBUS GPIO of Origen arm64: dts: exynos: fix polarity of "enable" line of NFC chip in TM2 arm64: dts: uniphier: Add L2 cache node arm64: dts: uniphier: Remove compatible "snps,dw-pcie" from pcie node arm64: dts: uniphier: Fix opp-table node name for LD20 arm64: dts: uniphier: Add USB-device support for PXs3 reference board arm64: dts: uniphier: Add ahci controller nodes for PXs3 arm64: dts: uniphier: Use GIC interrupt definitions arm64: dts: uniphier: Rename gpio-hog nodes arm64: dts: uniphier: Rename usb-glue node for USB3 to usb-controller arm64: dts: uniphier: Rename usb-phy node for USB2 to usb-controller arm64: dts: uniphier: Rename pvtctl node to thermal-sensor ARM: dts: uniphier: Remove compatible "snps,dw-pcie-ep" from pcie-ep node ARM: dts: uniphier: Move interrupt-parent property to each child node in uniphier-support-card ARM: dts: uniphier: Add ahci controller nodes for PXs2 ARM: dts: uniphier: Add ahci controller nodes for Pro4 ARM: dts: uniphier: Use GIC interrupt definitions ARM: dts: uniphier: Rename gpio-hog node ...

2022-10-06perf stat: Fix cpu check to use id.cpu.cpu in aggr_printout()Athira Rajeev
'perf stat' has options to aggregate the counts in different modes like per socket, per core etc. The function "aggr_printout" in util/stat-display.c which is used to print the aggregates, has a check for cpu in case of AGGR_NONE. This check was originally using condition : "if (id.cpu.cpu > -1)". But this got changed after commit df936cadfb58 ("perf stat: Add JSON output option"), which added option to output json format for different aggregation modes. After this commit, the check in "aggr_printout" is using "if (id.core > -1)". The old code was using "id.cpu.cpu > -1" while the new code is using "id.core > -1". But since the value printed is id.cpu.cpu, fix this check to use cpu and not core.

2022-10-06ftrace: Create separate entry in MAINTAINERS for function hooksSteven Rostedt (Google)
The function hooks (ftrace) is a completely different subsystem from the general tracing. It manages how to attach callbacks to most functions in the kernel. It is also used by live kernel patching. It really is not part of tracing, although tracing uses it. Create a separate entry for FUNCTION HOOKS (FTRACE) to be separate from tracing itself in the MAINTAINERS file. Perhaps it should be moved out of the kernel/trace directory, but that's for another time.

2022-10-06perf test: Introduce script for data symbol testingLeo Yan
The test is designed with a data structure with 64-byte alignment, it has two fields "data1" and "data2", and other fields are reserved. Using the "perf mem" command, we can record and report memory samples for a self-contained workload with 1 second duration. If no samples are obtained for the data structure "buf1", it reports failure; and by checking the offset in structure "buf1", if the memory samples aren't for the "data1" and "data2" fields, it means wrong data symbol parsing and returns failure.

2022-10-07powerpc: Don't add __powerpc_ prefix to syscall entry pointsMichael Ellerman
When using syscall wrappers the __SYSCALL_DEFINEx() and related macros add a "__powerpc_" prefix to all syscall entry points. So for example sys_mmap becomes __powerpc_sys_mmap. This risks breaking workflows and tools that expect the old naming scheme. At a minimum setting a breakpoint on eg. sys_mmap with gdb no longer works. There seems to be no compelling reason to add the "__powerpc_" prefix, other than that it follows what some other arches do (x86, arm64, s390). But unlike other arches powerpc doesn't always enable syscall wrappers, so the syscall entry points can change name depending on CONFIG options. For those reasons drop the "__powerpc_" prefix, reverting to the existing naming. Doing so reveals two prototypes in signal.h that have the incorrect type when syscall wrappers are enabled. There are already prototypes for both functions in syscalls.h, so drop the ones from signal.h.

Commit ae626eb97376 ("ARM/dma-mapping: use dma-direct unconditionally") caused a regression on the mvebu platform, wherein devices that are dma-coherent are marked as dma-noncoherent, because although mvebu_hwcc_notifier() after that commit still marks then as coherent, the arm_coherent_dma_ops() function, which is called later, overwrites this setting, since it is being called from drivers/of/device.c with coherency parameter determined by of_dma_is_coherent(), and the device-trees do not declare the 'dma-coherent' property.
