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.
