Inorder to support large effective address range (512TB), we want to increase the virtual address bits to 68. But we do have platforms like p4 and p5 that can only do 65 bit VA. We support those platforms by limiting context bits on them to 16. The protovsid -> vsid conversion is verified to work with both 65 and 68 bit va values. I also documented the restrictions in a table format as part of code comments. Signed-off-by:
