I think 64bit entry should be good for x86_64. When we start supporting this new system call on x86(32bit), then we can implement 32bit entry support (which should not be hard). I have no plans to implement 16bit entry support. I just wanted to mention explicitly what is currently supported. Thanks Vivek
