Pull RISC-V updates from Paul Walmsley - Add initial definitions and discovery for the Smcsrind, Sscsrind, Smcntrpmf, Ssccfg, Smcdeleg, Zicclsm, Ziccamoa, Ziccif, Ziccrse, Za64rs, and Ssqosid RISC-V ISA extensions - Improve the RISC-V update_mmu_cache_range() implementation by using flush-by-ASID, enabling performance improvements on microarchitectures that support related optimizations; and by taking advantage of the Svinval RISC-V ISA extension on microarchitectures that support it - Shrink CFI shadow stack allocation further (to 512MB) to save virtual address space (and physical memory on systems with strict overcommit policies) - Add initial CPU context switch support for QoS tagging (Ssqosid) - Change our vector misaligned access speed test code to be synchronous, avoiding a bunch of bugs related to unnecessary asynchronicity - Enable ARCH_HAS_ACPI_TABLE_UPGRADE for RISC-V to help with ACPI table debugging (similar to ARM64 and x86) - Extract vDSO section offsets at build time, rather than run time, to avoid the boot time overhead - Use assembler directives to control the use of instructions from the RISC-V ISA extensions Zacas and Zabha, rather than compiler -march flags that could affect the whole kernel (similar to ARM64) - Add a kselftest for kprobes support for the c.jal instruction on RISC-V - When UEFI runtime services are available, use them to restart and power off - Fix ARCH_HAS_ACPI_TABLE_UPGRADE for RISC-V by adding a missing include file to the ACPI code - Move contiguous DMA memory reservation later in the boot, to ensure that the correct global and per-node pools are allocated when CONFIG_CMA_SIZE_PERNUMA is enabled - Disallow probes on breakpoint handlers to avoid recursing indefinitely into do_trap_break() - Patch the compat vDSO during runtime alternatives processing, not only the standard vDSO - Remove some leftover XIP support elements missed by commit 9b3a2be84803 ("riscv: Remove support for XIP kernel") - Fix broadcast timer switching in ACPI LPI power states by implementing a RISC-V version of arch_get_idle_state_flags() - Miscellaneous fixes, including: vDSO makefile simplification; marking our default_power_off() as __noreturn; error path fixes in the PMU SBI perf driver; RISC-V extension capitalization consistency; the use of BIT() macros in one of our include files; and some documentation fixes * tag 'riscv-for-linus-7.3-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (39 commits) RISC-V: hwprobe: Use BIT macro to avoid warnings riscv: alternative: Also patch the compat vDSO riscv: alternative: Use the statically extracted vDSO section offsets riscv: vdso: Add symbols for the alternative section boundaries riscv: Add Ziccamoa, Ziccif, Ziccrse, and Za64rs to cpufeature and hwprobe riscv: Add Zicclsm to cpufeature and hwprobe riscv: cpufeature: Clarify ISA spec version for canonical order riscv: Standardize extension capitalization riscv: kprobes: Prevent probes in breakpoint handlers riscv: cmpxchg: Use .option arch for Zacas and Zabha riscv: acpi: Handle LPI architectural context loss flags riscv: further remove XIP riscv: Add support for srmcfg CSR from Ssqosid extension riscv: Detect the Ssqosid extension dt-bindings: riscv: Add Ssqosid extension description dt-bindings: riscv: add Counter delegation ISA extensions description RISC-V: Add Ssccfg/Smcdeleg ISA extension definition and parsing RISC-V: Add Ssccfg extension CSR definition dt-bindings: riscv: add Smcntrpmf ISA extension description RISC-V: Add Smcntrpmf extension parsing ...

RISC-V Devicetrees for v7.3 Sophgo: The changes of this PR are all for CV18xx serials. There are three major changes. The first is to allow DMA multiplexer setting channel number for DMA controller; the second is to add initial RISC-V support for "Duo S" board, which uses SG2000, a dual-arch SoC (RISC-V and ARM64); the third is to add support for "Duo 256M" board, another dev-board based on SG2002 SoC.
