Because I am adding new hypercall (do_xenpmu_op) and if I added it right
after do_tmem_op (which is number 38) then it would become number 39.
xen.h appears to want to reserve 39 for something else so I had to put a
placeholder there. And now do_xenpmu_op becomes number 40.
(And to answer your previous email --- I will be posting v11 shortly)
