Merge tag 'riscv-for-linus-6.6-mw2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull more RISC-V updates from Palmer Dabbelt: - The kernel now dynamically probes for misaligned access speed, as opposed to relying on a table of known implementations. - Support for non-coherent devices on systems using the Andes AX45MP core, including the RZ/Five SoCs. - Support for the V extension in ptrace(), again. - Support for KASLR. - Support for the BPF prog pack allocator in RISC-V. - A handful of bug fixes and cleanups. * tag 'riscv-for-linus-6.6-mw2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (25 commits) soc: renesas: Kconfig: For ARCH_R9A07G043 select the required configs if dependencies are met riscv: Kconfig.errata: Add dependency for RISCV_SBI in ERRATA_ANDES config riscv: Kconfig.errata: Drop dependency for MMU in ERRATA_ANDES_CMO config riscv: Kconfig: Select DMA_DIRECT_REMAP only if MMU is enabled bpf, riscv: use prog pack allocator in the BPF JIT riscv: implement a memset like function for text riscv: extend patch_text_nosync() for multiple pages bpf: make bpf_prog_pack allocator portable riscv: libstub: Implement KASLR by using generic functions libstub: Fix compilation warning for rv32 arm64: libstub: Move KASLR handling functions to kaslr.c riscv: Dump out kernel offset information on panic riscv: Introduce virtual kernel mapping KASLR RISC-V: Add ptrace support for vectors soc: renesas: Kconfig: Select the required configs for RZ/Five SoC cache: Add L2 cache management for Andes AX45MP RISC-V core dt-bindings: cache: andestech,ax45mp-cache: Add DT binding documentation for L2 cache controller riscv: mm: dma-noncoherent: nonstandard cache operations support riscv: errata: Add Andes alternative ports riscv: asm: vendorid_list: Add Andes Technology to the vendors list ...
