As I said in the commit log, only x86, ia64 and alpha provide assembly code to replace the generic C code. The ll/sc archs that I have access to (ARM64, ppc) are all using the generic C code anyway. I actually had done some performance measurement on both those platforms and didn't see any performance difference. I didn't include them as they were using generic code before. I will rerun the tests after I twisted the generic C code. Thanks, Longman
