Pull RISC-V updates from Palmer Dabbelt: - Support for the new "riscv,isa-extensions" and "riscv,isa-base" device tree interfaces for probing extensions - Support for userspace access to the performance counters - Support for more instructions in kprobes - Crash kernels can be allocated above 4GiB - Support for KCFI - Support for ELFs in !MMU configurations - ARCH_KMALLOC_MINALIGN has been reduced to 8 - mmap() defaults to sv48-sized addresses, with longer addresses hidden behind a hint (similar to Arm and Intel) - Also various fixes and cleanups * tag 'riscv-for-linus-6.6-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (51 commits) lib/Kconfig.debug: Restrict DEBUG_INFO_SPLIT for RISC-V riscv: support PREEMPT_DYNAMIC with static keys riscv: Move create_tmp_mapping() to init sections riscv: Mark KASAN tmp* page tables variables as static riscv: mm: use bitmap_zero() API riscv: enable DEBUG_FORCE_FUNCTION_ALIGN_64B riscv: remove redundant mv instructions RISC-V: mm: Document mmap changes RISC-V: mm: Update pgtable comment documentation RISC-V: mm: Add tests for RISC-V mm RISC-V: mm: Restrict address space for sv39,sv48,sv57 riscv: enable DMA_BOUNCE_UNALIGNED_KMALLOC for !dma_coherent riscv: allow kmalloc() caches aligned to the smallest value riscv: support the elf-fdpic binfmt loader binfmt_elf_fdpic: support 64-bit systems riscv: Allow CONFIG_CFI_CLANG to be selected riscv/purgatory: Disable CFI riscv: Add CFI error handling riscv: Add ftrace_stub_graph riscv: Add types to indirectly called assembly functions ...
