#     Don't map the early shadow page read-only yet when creating the new
#     page tables for the real shadow memory, otherwise the memblock
#     allocations that immediately follows to create the real shadow pages
#     that are about to replace the early shadow page trigger a page fault
#     if they fall into the region being worked on at the moment.
