All of these steps succeed (the hypercall returns 0, and the argument indicating how many updates succeeded is 1 in both cases). But later, when switching into the context of this process, I try to update the user base pointer with

 HYPERVISOR_mmuext_op({MMUEXT_NEW_USER_BASEPTR, mfn of P}...).

Only x86/64 has a separate USER_BASEPTR. You want to use just MMUEXT_NEW_BASEPTR.
