Dan Williams da7bc9c57e x86/asm/memcpy_mcsafe: Remove loop unrolling ... In preparation for teaching memcpy_mcsafe() to return 'bytes remaining' rather than pass / fail, simplify the implementation to remove loop unrolling. The unrolling complicates the fault handling for negligible benefit given modern CPUs perform loop stream detection.
