Merge tag 'riscv-for-linus-6.11-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull more RISC-V updates from Palmer Dabbelt: - Support for NUMA (via SRAT and SLIT), console output (via SPCR), and cache info (via PPTT) on ACPI-based systems. - The trap entry/exit code no longer breaks the return address stack predictor on many systems, which results in an improvement to trap latency. - Support for HAVE_ARCH_STACKLEAK. - The sv39 linear map has been extended to support 128GiB mappings. - The frequency of the mtime CSR is now visible via hwprobe. * tag 'riscv-for-linus-6.11-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (21 commits) RISC-V: Provide the frequency of time CSR via hwprobe riscv: Extend sv39 linear mapping max size to 128G riscv: enable HAVE_ARCH_STACKLEAK riscv: signal: Remove unlikely() from WARN_ON() condition riscv: Improve exception and system call latency RISC-V: Select ACPI PPTT drivers riscv: cacheinfo: initialize cacheinfo's level and type from ACPI PPTT riscv: cacheinfo: remove the useless input parameter (node) of ci_leaf_init() RISC-V: ACPI: Enable SPCR table for console output on RISC-V riscv: boot: remove duplicated targets line trace: riscv: Remove deprecated kprobe on ftrace support 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 RISC-V: run savedefconfig for defconfig RISC-V: hwprobe: sort EXT_KEY()s in hwprobe_isa_ext0() alphabetically ACPI: NUMA: replace pr_info with pr_debug in arch_acpi_numa_init ACPI: NUMA: change the ACPI_NUMA to a hidden option ACPI: NUMA: Add handler for SRAT RINTC affinity structure ...
