Sounds good to me - I've merged this patch, will push it out after 
testing.

Based on Peter's feedback I'm delaying this - performance testing on at 
least one key ll/sc arch would be nice indeed.

Thanks,

Yes, I will twist the generic code to generate better code.

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
