GoKawiilLinux 7.5 to drop final MMX-optimized code from RAID XOR routines
A patch set to merge into mainline Linux 7.5, expected in 2027, will remove the kernel's last MMX-optimized code, located in the software RAID XOR routines, according to Phoronix. The change strips over 800 lines of code down to just 12 lines. Most other MMX-optimized code, including memory management routines, was already removed from Linux about five years ago.
