Otherwise, the most notable changes are to add some RISC-V-specific string function implementations, to remove XIP kernel support, to add hardware error exception handling, and to optimize our runtime unaligned access speed testing. A few comments on the motivation for removing XIP support. It's been broken in the RISC-V kernel for months. The code is not easy to maintain. Furthermore, for XIP support to truly be useful for RISC-V, we think that compile-time feature switches would need to be added for many of the RISC-V ISA features and microarchitectural properties that are currently implemented with runtime patching. No one has stepped forward to take responsibility for that work, so many of us think it's best to remove it until clear use cases and champions emerge. Summary: - Add Kunit correctness testing and microbenchmarks for strlen(), strnlen(), and strrchr() - Add RISC-V-specific strnlen(), strchr(), strrchr() implementations - Add hardware error exception handling - Clean up and optimize our unaligned access probe code - Enable HAVE_IOREMAP_PROT to be able to use generic_access_phys() - Remove XIP kernel support - Warn when addresses outside the vmemmap range are passed to vmemmap_populate() - Update the ACPI FADT revision check to warn if it's not at least ACPI v6.6, which is when key RISC-V-specific tables were added to the specification - Increase COMMAND_LINE_SIZE to 2048 to match ARM64, x86, PowerPC, etc. - Make kaslr_offset() a static inline function, since there's no need for it to show up in the symbol table - Add KASLR offset and SATP to the VMCOREINFO ELF notes to improve kdump support - Add Makefile cleanup rule for vdso_cfi copied source files, and add a .gitignore for the build artifacts in that directory - Remove some redundant ifdefs that check Kconfig macros - Add missing SPDX license tag to the CFI selftest - Simplify UTS_MACHINE assignment in the RISC-V Makefile - Clarify some unclear comments and remove some superfluous comments - Fix various English typos across the RISC-V codebase" * tag 'riscv-for-linus-7.1-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (31 commits) riscv: Remove support for XIP kernel riscv: Reuse compare_unaligned_access() in check_vector_unaligned_access() riscv: Split out compare_unaligned_access() riscv: Reuse measure_cycles() in check_vector_unaligned_access() riscv: Split out measure_cycles() for reuse riscv: Clean up & optimize unaligned scalar access probe riscv: lib: add strrchr() implementation riscv: lib: add strchr() implementation riscv: lib: add strnlen() implementation lib/string_kunit: extend benchmarks to strnlen() and chr searches lib/string_kunit: add performance benchmark for strlen() lib/string_kunit: add correctness test for strrchr() lib/string_kunit: add correctness test for strnlen() lib/string_kunit: add correctness test for strlen() riscv: vdso_cfi: Add .gitignore for build artifacts riscv: vdso_cfi: Add clean rule for copied sources riscv: enable HAVE_IOREMAP_PROT riscv: mm: WARN_ON() for bad addresses in vmemmap_populate() riscv: acpi: update FADT revision check to 6.6 riscv: add hardware error trap handler support ... 2026-04-24T16:41:58+00:00 Linus Torvalds torvalds@linux-foundation.org 2026-04-24T16:41:58+00:00 urn:sha1:64edfa65062dc4509ba75978116b2f6d392346f5 Pull networking deletions from Jakub Kicinski: "Delete some obsolete networking code Old code like amateur radio and NFC have long been a burden to core networking developers. syzbot loves to find bugs in BKL-era code, and noobs try to fix them. If we want to have a fighting chance of surviving the LLM-pocalypse this code needs to find a dedicated owner or get deleted. We've talked about these deletions multiple times in the past and every time someone wanted the code to stay. It is never very clear to me how many of those people actually use the code vs are just nostalgic to see it go. Amateur radio did have occasional users (or so I think) but most users switched to user space implementations since its all super slow stuff. Nobody stepped up to maintain the kernel code. We were lucky enough to find someone who wants to help with NFC so we're giving that a chance.
