nit: I also thought that the hyp_create_mappings function names are a
bit confusing, since there's the create_hyp_mappings functions which
use the aforementioned *hyp_pgtable.

Sure, happy to re-name those (and hyp_pgtable above). Any suggestions?

Perhaps something to indicate that these are temporary, tmp_ or
bootstrap_ maybe?

Hmm, the thing is these are temporary only in protected mode, they're
permanent otherwise :/

Perhaps I could prefix the protected pgtable (and associated functions)
with 'pkvm_' or so? Marc, any preferences?

Thanks,
Quentin
