Merge tag 'riscv-for-linus-6.5-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V updates from Palmer Dabbelt: - Support for ACPI - Various cleanups to the ISA string parsing, including making them case-insensitive - Support for the vector extension - Support for independent irq/softirq stacks - Our CPU DT binding now has "unevaluatedProperties: false" * tag 'riscv-for-linus-6.5-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (78 commits) riscv: hibernate: remove WARN_ON in save_processor_state dt-bindings: riscv: cpus: switch to unevaluatedProperties: false dt-bindings: riscv: cpus: add a ref the common cpu schema riscv: stack: Add config of thread stack size riscv: stack: Support HAVE_SOFTIRQ_ON_OWN_STACK riscv: stack: Support HAVE_IRQ_EXIT_ON_IRQ_STACK RISC-V: always report presence of extensions formerly part of the base ISA dt-bindings: riscv: explicitly mention assumption of Zicntr & Zihpm support RISC-V: remove decrement/increment dance in ISA string parser RISC-V: rework comments in ISA string parser RISC-V: validate riscv,isa at boot, not during ISA string parsing RISC-V: split early & late of_node to hartid mapping RISC-V: simplify register width check in ISA string parsing perf: RISC-V: Limit the number of counters returned from SBI riscv: replace deprecated scall with ecall riscv: uprobes: Restore thread.bad_cause riscv: mm: try VMA lock-based page fault handling first riscv: mm: Pre-allocate PGD entries for vmalloc/modules area RISC-V: hwprobe: Expose Zba, Zbb, and Zbs RISC-V: Track ISA extensions per hart ...
