From: Milan Tripkovic <[email protected]> Add an optimized assembly implementation of memchr() for RISC-V. The implementation uses word-aligned loads and Zbb optimizations where available, with a fallback for non-Zbb hardware.
The series also includes KUnit tests for functional verification and performance benchmarking.
