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.
