Merge tag 'riscv-for-linus-6.3-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V updates from Palmer Dabbelt:
"There's a bunch of fixes/cleanups throughout the tree as usual, but we
also have a handful of new features:
- Various improvements to the extension detection and alternative
patching infrastructure
- Zbb-optimized string routines
- Support for cpu-capacity in the RISC-V DT bindings
- Zicbom no longer depends on toolchain support
- Some performance and code size improvements to ftrace
- Support for ARCH_WANT_LD_ORPHAN_WARN
- Oops now contain the faulting instruction"
