[Xen-devel] pagetable handling in xen

i'm trying to understand how xen handles pagetables, but i'm a bit

1. where is a new domain's memory mapping initialized in xen?
2. what're the differences between idle_pg_table and linear_pg_table and
are they indexed by guest linear page #s or hardware page #s?
3. [this is more of an affirmation, than a question] xen can't arbitrarily
access *any* physical page because it doesn't map all of physical
memory (eg, like linux does from PAGE_OFFSET)?
