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.
