Pull RISC-V updates from Palmer Dabbelt: - Improvements to the CPU topology subsystem, which fix some issues where RISC-V would report bad topology information. - The default NR_CPUS has increased to XLEN, and the maximum configurable value is 512. - The CD-ROM filesystems have been enabled in the defconfig. - Support for THP_SWAP has been added for rv64 systems. There are also a handful of cleanups and fixes throughout the tree. * tag 'riscv-for-linus-6.1-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: enable THP_SWAP for RV64 RISC-V: Print SSTC in canonical order riscv: compat: s/failed/unsupported if compat mode isn't supported RISC-V: Increase range and default value of NR_CPUS cpuidle: riscv-sbi: Fix CPU_PM_CPU_IDLE_ENTER_xyz() macro usage perf: RISC-V: throttle perf events perf: RISC-V: exclude invalid pmu counters from SBI calls riscv: enable CD-ROM file systems in defconfig riscv: topology: fix default topology reporting arm64: topology: move store_cpu_topology() to shared code
