So as I mentioned before, I am happy to loose the Kconfig option, but
then we need some sensible default value. In our case we could be cheeky

not matter for 4.9.
I don't think we need a sensible default value and IHMO there is none. I would
left the user to decide the exact number.
In that case, the command line parameter becomes mandatory: we need to
force the user to specify it as we do for dom0_mem today.
Not really. We should use the hardware value by default. If a user
thinks the number allocated is too big for his use case, then it can
limit using the command line.
Anyway, I will not oppose to make this command option mandatory when ITS
is in use.
