This harmonizes all virtual addressing modes which can now all map (PGDIR_SIZE * PTRS_PER_PGD) / 4 of physical memory. The RISCV implementation of KASAN requires that the boundary between shallow mappings are aligned on an 8G boundary. In this case we need VMALLOC_START to be 8G aligned. So although we only need to move the start of the linear mapping down by 4GiB to allow 128GiB to be mapped, we actually move it down by 8GiB (creating a 4GiB hole between the linear mapping and KASAN shadow space) to maintain the alignment requirement.

Add support for the stackleak feature. Whenever the kernel returns to user space the kernel stack is filled with a poison value. At the same time, disables the plugin in EFI stub code because EFI stub is out of scope for the protection.

Many CPUs implement return address branch prediction as a stack. The RISCV architecture refers to this as a return address stack (RAS). If this gets corrupted then the CPU will mispredict at least one but potentally many function returns. There are two issues with the current RISCV exception code: - We are using the alternate link stack (x5/t0) for the indirect branch which makes the hardware think this is a function return. This will corrupt the RAS. - We modify the return address of handle_exception to point to ret_from_exception. This will also corrupt the RAS. Testing the null system call latency before and after the patch: Visionfive2 (StarFive JH7110 / U74) baseline: 189.87 ns patched: 176.76 ns Lichee pi 4a (T-Head TH1520 / C910) baseline: 666.58 ns patched: 636.90 ns Just over 7% on the U74 and just over 4% on the C910.

Before cacheinfo can be built correctly, we need to initialize level and type. Since RISC-V currently does not have a register group that describes cache-related attributes like ARM64, we cannot obtain them directly, so now we obtain cache leaves from the ACPI PPTT table (acpi_get_cache_info()) and set the cache type through split_levels.

Since commit 7caa9765 ("ftrace: riscv: move from REGS to ARGS"), kprobe on ftrace is not supported by riscv, because riscv's support for FTRACE_WITH_REGS has been replaced with support for FTRACE_WITH_ARGS, and KPROBES_ON_FTRACE will be supplanted by FPROBES. So remove the deprecated kprobe on ftrace support, which is misunderstood.

Charlie Jenkins <charlie@rivosinc.com> says: All extensions, both standard and vendor, live in one struct "riscv_isa_ext". There is currently one vendor extension, xandespmu, but it is likely that more vendor extensions will be added to the kernel in the future. As more vendor extensions (and standard extensions) are added, riscv_isa_ext will become more bloated with a mix of vendor and standard extensions. This also allows each vendor to be conditionally enabled through Kconfig. * b4-shazam-merge: riscv: cpufeature: Extract common elements from extension checking riscv: Introduce vendor variants of extension helpers riscv: Add vendor extensions to /proc/cpuinfo riscv: Extend cpufeature.c to detect vendor extensions Link: https://lore.kernel.org/r/20240719-support_vendor_extensions-v3-0-0af7587bbec0@rivosinc.comSigned-off-by: Palmer Dabbelt <palmer@rivosinc.com>

Instead of grouping all vendor extensions into the same riscv_isa_ext that standard instructions use, create a struct "riscv_isa_vendor_ext_data_list" that allows each vendor to maintain their vendor extensions independently of the standard extensions. xandespmu is currently the only vendor extension so that is the only extension that is affected by this change. An additional benefit of this is that the extensions of each vendor can be conditionally enabled. A config RISCV_ISA_VENDOR_EXT_ANDES has been added to allow for that.

It's been a while since this was run, and there's a few things that have changed. Firstly, almost all of the Renesas stuff vanishes because the config for the RZ/Five is gated behind NONPORTABLE. Several options (like CONFIG_PM) are removed as they are the default values. To retain DEFVFREQ_THERMAL and BLK_DEV_THROTTLING, add PM_DEVFREQ and BLK_CGROUP respectively.

Pull i2c fixes from Wolfram Sang: "The I2C core gains documentation updates for the testunit, a cleanup regarding unneeded 'driver_data' and more sanity checks in the char device. For the host drivers, this release includes significant updates, with the primary change being the renaming from "master/slave" to "controller/target" to adhere to I2C v7 and SMBus 3.2 standards. New Support: - Added support for Intel Arrow Lake-H - Added I2C support in the Arioha SoC by linking the Mediatek I2C controller Cleanups: - Added the MODULE_DESCRIPTION() macro, resolving a modpost warning in the ALi 1563 Southbridge driver. - Constified the regmap_config declaration in the i2c-designware driver. - Improved the coding style in the Renesas R-Car driver by removing unnecessary semicolons after brackets. General improvements: - In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with RUNTIME_PM_OPS to enable waking up the controller during suspend() before suspend_noirq() kicks in. - Improved logging in the Xilinx driver. - Added a warning (WARN()) in the Renesas R-Car driver for spurious interrupts. DTS Changes: - Removed address-cell and size-cell from the Atmel at91sam, nVidia Tegra 20, and Samsung S3c2410 devices. - Fixed Texas Instruments OMAP4 I2C controller to comply with the i2c-controller.yaml schema. - Improved indentation in DTS examples for several I2C devices. - Converted the NXP LPC1788 binding to the dt-schema. - Added documentation for the compatible string thead,th1520-i2c. - Added the "power-domains" property for the Meson I2C driver.

Pull sound updates from Takashi Iwai: "Lots of changes in this cycle, but mostly for cleanups and refactoring. Significant amount of changes are about DT schema conversions for ASoC at this time while we see other usual suspects, too. Some highlights below: Core: - Re-introduction of PCM sync ID support API - MIDI2 time-base extension in ALSA sequencer API ASoC: - Syncing of features between simple-audio-card and the two audio-graph cards - Support for specifying the order of operations for components within cards to allow quirking for unusual systems - Lots of DT schema conversions - Continued SOF/Intel updates for topology, SoundWire, IPC3/4 - New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS v2.5 and WCD937x, Realtek RT1318 and RT1320 and Texas Instruments PCM5242 HD-audio: - More quirks, Intel PantherLake support, senarytech codec support - Refactoring of Cirrus codec component-binding Others: - ALSA control kselftest improvements, and fixes for input value checks in various drivers" * tag 'sound-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (349 commits) kselftest/alsa: Log the PCM ID in pcm-test kselftest/alsa: Use card name rather than number in test names ALSA: hda/realtek: Fix the speaker output on Samsung Galaxy Book Pro 360 ALSA: hda/tas2781: Add new quirk for Lenovo Hera2 Laptop ALSA: seq: ump: Skip useless ports for static blocks ALSA: pcm_dmaengine: Don't synchronize DMA channel when DMA is paused ALSA: usb: Use BIT() for bit values ALSA: usb: Fix UBSAN warning in parse_audio_unit() ALSA: hda/realtek: Enable headset mic on Positivo SU C1400 ASoC: tas2781: Add new Kontrol to set tas2563 digital Volume ASoC: codecs: wcd937x: Remove separate handling for vdd-buck supply ASoC: codecs: wcd937x: Remove the string compare in MIC BIAS widget settings ASoC: codecs: wcd937x-sdw: Fix Unbalanced pm_runtime_enable ASoC: dt-bindings: cirrus,cs42xx8: Convert to dtschema ASoC: cs530x: Remove bclk from private structure ASoC: cs530x: Calculate proper bclk rate using TDM ASoC: dt-bindings: cirrus,cs4270: Convert to dtschema firmware: cs_dsp: Rename fw_ver to wmfw_ver firmware: cs_dsp: Clarify wmfw format version log message firmware: cs_dsp: Make wmfw and bin filename arguments const char * ...

Pull clk updates from Stephen Boyd: "This a large collection of clk driver updates and a handful of new SoC clk driver support. We have the usual Qualcomm clk drivers, along with clk drivers for the Sophgo and T-Head vendors, all to support some new SoCs. Nothing in particular stands out to me in the updates. There's the interconnect clk driver which exposes clks as interconnects, crossing subsystems. There's a bunch of janitorial things that are improving drivers in general like kmemdup_array() or fixing error paths. But overall the updates look normal to fix the description data which is usually the stuff that's wrong and/or untested. Core: - Skip gate basic type KUnit tests on s390 due to lack of MMIO emulation New Drivers: - AP sub-system clock controller in the T-Head TH1520 - Sophgo Sophon sg2042 clk driver - Qualcomm SM7150 camera, display and video clk drivers - Qualcomm QCM2290 GPU clk driver - Qualcomm QCS8386/QCS8084 NSS clk driver - Qualcomm SM8650 camera and video drivers Updates: - Add reset support to Airoha EN7581 clk driver - Add MODULE_DESCRIPTIONs to various clk drivers - Introduce helper logic to expose clock controllers as simple interconnect providers - Use the interconnect helper above on Qualcomm ipq9574 - Add CLK_SET_RATE_PARENT to the remaining USB pipe clocks on Qualcomm X1Elite - Improve error handling in Qualcomm kpss-xcc driver - Mark Qualcomm SC8280XP LPASS clock controller regmap_config const - Export more clocks for Rockchip rk3128 peripherals - Convert Rockchip clk drivers to use kmemdup_array() - Drop CLK_NR_CLKS from Rockchip rk3128 and rk3188 binding headers - Make qcom_cc_really_probe() take a struct device to allow reuse in non-platform-drivers - Introduce prepare-only branch clock ops in the qcom clk driver to support clocks on buses that take locks - Describe parent/child relationship for Qualcomm SC7280 camera GDSCs - Support Qualcomm Huayra 2290 alpha PLL - Adjust the highest SDCC clock frequency on Qualcomm IPQ6018 to match HS200 support - Add missing PCIe PIPE clocks on Qualcomm IPQ9574 - Fix various configurations and properties in the Qualcomm SA8775P, X1E80100 and SM7280 drivers - Park Qualcomm SM8350 GPU RCGs on XO while disabled - Remove unused CONFIG_QCOM_RPMCC Kconfig symbol - exynos-clkout: Remove usage of of_device_id table as .of_match_table, because the driver is instantiated as MFD cell, not as standalone platform driver. Populated .of_match_table confused people few times to convert the code to device_get_match_data(), which broke the driver - Mark one Samsung UFS clock as critical, because having it off stops the system from shutdown - Use kmemdup_array() when applicable - Remove unused 'struct gates_data' from old sunxi driver library - Add GPADC clock and reset for Allwinner H616 - Minor Amlogic S4 clock fixes - DT bindings Yaml conversion of the Amlogic AXG audio controller - Amlogic C3 clock controllers support - Amlogic clk flag added to skip init of already enabled PLLs and avoid relocking - Amlogic A1 DT bindings updates for system pll support - Add missing MODULE_DESCRIPTION where necessary - Remove obsolete clock DT binding header files - Add Battery Backup (VBATTB) and I2C clocks, resets, and power domains on Renesas RZ/G3S - Add audio clocks on Renesas R-Car V4M - Add video capture (ISPCS, CSI-2, VIN) clocks on Renesas R-Car V4M" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (135 commits) clk: thead: Add support for T-Head TH1520 AP_SUBSYS clocks dt-bindings: clock: Document T-Head TH1520 AP_SUBSYS controller clk: sophgo: Avoid -Wsometimes-uninitialized in sg2042_clk_pll_set_rate() clk/sophgo: Using BUG() instead of unreachable() in mmux_get_parent_id() clk: mxs: Use clamp() in clk_ref_round_rate() and clk_ref_set_rate() clk: sunxi-ng r40: Constify struct regmap_config clk: en7523: fix rate divider for slic and spi clocks clk: lpc32xx: Constify struct regmap_config clk: xilinx: Constify struct regmap_config clk: en7523: Remove PCIe reset open drain configuration for EN7581 clk: en7523: Remove pcie prepare/unpreare callbacks for EN7581 SoC clk: en7523: Add reset-controller support for EN7581 SoC dt-bindings: clock: airoha: Add reset support to EN7581 clock binding dt-bindings: clock: mediatek: Document reset cells for MT8188 sys clk: mediatek: mt8173-infracfg: Handle unallocated infracfg when module dt-bindings: clock: mediatek: add syscon compatible for mt7622 pciesys dt-bindings: clock: sprd,sc9860-clk: convert to YAML dt-bindings: clock: qoriq-clock: convert to yaml format clk: qcom: Park shared RCGs upon registration clk: qcom: ipq9574: Use icc-clk for enabling NoC related clocks ...
