Please explain in detail why they are needed.

Actually, start_secondary is not needed anymore, I removed its use at some point.

initial_pg_pmd (together with initial_page_table) are not really required --- I just used them for temporary page tables in the hvmlite startup code instead of allocating dedicated pages for that. Perhaps there is other (Xen-specific) area that I can use for that. Once we jump to startup_32 these tables are no longer in use.
