Of hand that looks good to me now.
It would be nice if we keep the separation of one patch for each driver.
But that would mean we need something like adding the size field first,
patch all drivers and then remove num_pages which isn't a good approach
either.
But please make sure that the Intel CI systems are happy with that.
