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
